ab switch pedal Lehle Dual SGoS ABY Switcher Pedal – Chicago Music ExchangeThe LEHLE DUAL SGOS is the second evolutionary stage of the highly successful programmable switcher for two amps plus tuner. This unit makes it possible to play through two amplifiers individually or simultaneously, either as a stand alone unit or in a network with other Lehle SGoS switchers.

The LEHLE DUAL SGOS is the second evolutionary stage of the highly successful programmable switcher for two amps plus tuner. This unit makes it possible to play through two amplifiers individually or simultaneously, either as a stand-alone unit or in a network with other Lehle SGoS switchers. A particularly popular combination is the LEHLE DUAL SGOS with the LEHLE D.LOOP SGOS. Programming is as easy and intuitive as you would expect from a Lehle product, and can also be done remotely, using MIDI program change commands. Hum loops are completely excluded, thanks to electrical isolation of outputs A and B by the Lehle LTHZ high-end transformer. Gold-plated-contact relays, ground switches and phase inverters assure the full, loss-free guitar sound. The potentiometers are in the signal path when output A and B are active simultaneously, and the volume of the two amps can be balanced - producing a third sound you've never heard before! Output T, basically intended for instrument tuners, can also be used for a third amp or for a second channel for amp B, opening up even more potentials. The gold-plated-contact relays feature active pop-and-click suppression, outputs A and B can be muted for undisturbed instrument tuning. Welcome to the new Duality!


GOLD-PLATED RELAYS & SWITCHES
The signal from the pickups of an electric guitar or bass is so weak that poor-quality cables, cold joints and cheap contact materials ruin your sound. Switch contacts need to be made of special materials to permit loss-free switching of these low-level signals. All Lehle switchers feature special relays and slide switches with gold-plated contacts for totally reliable, absolutely zero-loss switching.

LEHLE TRANSFORMER HZ
Hum loops and phase cancellations can occur as soon as the signal from an instrument is fed to more than one amp simultaneously. The one and only remedy for this is a high-quality transformer. Standard transformers modify the tone of electric guitars and basses very severely, since they are not designed to handle the low-strength high-impedance signals generated by instrument pickups. The Lehle LTHZ, on the other hand, has been specially conceived for use with these high-impedance signals, preserving instrument tone and the interaction between instrument and amp and eliminating hum loops.

LEHLE FOOTSWITCH
The easy-action mushroom-shaped buttons characteristic of LEHLE products are mounted in the cover, so that your foot pressure is transmitted indirectly only, via a spring. Thus the electronics board is not exposed to mechanical loads, making your LEHLE virtually indestructible and guaranteeing years of trouble-free switching.

ADJUSTABLE GAIN
Adjustment of volume or distortion using a gain controller is a vital feature in many situations. The gain controllers on the corresponding Lehle products feature black anodized aluminium knobs set back into the housing so that they can be easily fingertip rotated but keep their settings during performances and transportation.

MIDI INTERFACE
By means of the MIDI interface, control information can be exchanged. All LEHLE products with the MIDI symbol are able to be networked with external equipment, in order to control it and/or be controlled.

STEREO
Many effects units feature stereo outputs. Or: instruments frequently have two pickup systems, e.g. a combination of conventional magnetic and Piezo types, to emulate an acoustic sound. Lehle accessories are ideal for trouble-free routing of such dual-channel stereo signals. All stereo-capable Lehle products are, of course, also suitable for mono operation.

BALANCED OUTPUT
Equipped with a standard TRS-socket for balanced output signals if needed.

NO HUM LOOPS
All Lehle products not featuring an LTHZ transformer and bearing this symbol switch the signal ground parallel to the signal itself via switches or relays with gold-plated contacts. Hum loops are thus effectively eliminated when switching backwards and forwards between different signal sources without, for example, simultaneous activation of two amps.

OK for the price, but overall comfort is avergae
Size: 934-Z, Color: Mustard
Easy to put together, color (mustard) accurate to images, and while I understand this is not a high-end chair, I feel like it still needs to be rated for its quality. Pros: the seat cushions are fairly comfortable and it rolls well. Adjustable footrest is easy enough and mostly sturdy. Cons: For a tall office chair, it doesn't go up high enough. I actually had to lower my standing desk to sit at it, which then isn't where I want it when I'm standing now. It's also a bit wobbly. The seat area's attachment to the post isn't as solid as it should be for a tall chair, so while sitting, it does tend to lean/slope forward and wobble side to side. The lumbar support is not adjustable, so I'm not even really sure what it does. And the armrests are not very comfortable to use. Since they are hard plastic, they are just a bit too rigid to rely on for any comfort. They are basically there to hold on to when you're getting out of the chair.

Good Value for a Tall Chair
Size: 934W-Z, Color: White
I have received this chair just today and would like to give my first impressions of it. Height is super adjustable as well as the foot rest. My desk is very tall (~34 inches vs standard ~29 inches) and does not suit a standard height chair. This chair's height is enough to sit comfortably at mybut also still having adjustment to be even higher. Lumbar support is a manual adjustment that can be adjusted by sliding the lumbar piece up or down and it seems it can be tiled as well. No reclining feature or slight backrest tilt adjustment. I'm used to my chairs reclining so it feels a little awkward siting in a flat base and straight backrest. I feel like I'm sitting too forward or leaning forward slightly but is probably something I can get use to. Easy to put together and feels very sturdy. Plastic parts of chair are made from a really sturdy plastic, like playhouse plastic materials. Wheels roll around carpet easily. Mesh seems to be a strong material, though the mesh feels kind itchy on bare skin. Overall, I think this is a good chair to get if you're needing a tall chair for a good value and can sacrifice no backrest tilt.

Excellent value for money!
Size: 934W-Z, Color: Black, Size: 934W-Z, Color: Black
I absolutely love this office chair! I needed a chair that could support my standing desk without sacrificing comfort, and this one completely exceeded my expectations. It's incredibly sturdy and durable, well-made, and the height adjustment is super convenient, making it easy to find the perfect fit. Even during long hours of work, the seat is comfortable, and the ergonomic design effectively reduces pressure on my back and legs. I love its clean, modern look—it fits my home office perfectly. Assembly was quick and easy, and for this price, the quality is absolutely fantastic!

Perfect chair!
Size: 934-Z, Color: Blue, Size: 934-Z, Color: Blue
I have an adjustable-height desk (also purchased from Amazon) and needed a drafting chair for those times when my body gets tired of standing. This chair fits the bill and then some! I put it together myself; it took me about an hour, but would take me about half that next time, since now I know what to do (and what NOT to do!). All the parts were there; there are even spare parts (see photo). All the holes were drilled in exactly the right places, too, which isn't always the case when I buy things from Amazon (my standing desk is a great example). The chair fits me; I'm short (5'3.5"), and often the seats of furniture are too deep for me to rest my feet flat on the floor. The depth of the seat on this chair is just a little over 18 inches, and with the adjustable footrest ring, it's perfect. I don't think a tall or heavy person would fit in it, to be honest. But it's perfect for those of us who are vertically challenged. I love that it glides easily on my hardwood floors and that it turns 360 degrees. The chair comes in numerous luscious colors, so take your pick! It is very sturdy, has good lumbar support, and the seat and seat back are very comfortable. And the arms flip up, which was an absolute must when I was shopping for this chair. I got it on sale, too -- $109.00 -- and I'm delighted with this purchase.
