RUBY RED BOOSTER - A COMBINATION OF TWO BOOSTERS AND A SWITCHABLE BUFFER

You can use Ruby Red Booster as a treble booster, a clean boost or an overdrive unit or any combination of the above. Also, it can be used with or without the buffer. 

The Treble Booster is a fine-tuned booster for just the right treble frequency with carefully designed bandwidth and an optimized slope of bass cut. The booster circuit is designed to overdrive the amplifier inputs from nice shimmer to heavy overdrive, thanks to the massive 40dB of boost. The booster is tuned so that it produces musical distortion by itself on higher boost settings. 

You can control the total level of the two boosters with the Master Volume control and also use the Master Volume to achieve distortion from the unit. 

We truly think Ruby Red Booster is the best sounding and most versatile booster for electric guitar on the market!

CONTROLS
MASTER: This is a volume control that is located directly after the booster circuit and when set to max it is just a resistor to ground. This control sets the final output and it can be used to control the output when the pedal is used for overdrive (Boost turned up). TREBLE: Set treble boost from zero to about 15dB. The treble frequency and bandwidth are carefully tuned with an optimized bass slope. BOOST: The gain of the booster and can be set from unity to about 40dB of boost. When this control is cranked the unit will distort within itself. BUFFER: Inside the pedal, there is a switch for a high-quality buffer. You can set the pedal for true bypass mode or “buffer on” in bypass mode. We recommend using a buffer in your signal chain to help with the treble and gain loss from using many pedals and/or long cables. Pedals are shipped “buffer on”.The Mad Professor RRB Buffer is an amplifier with a voltage gain of exactly 1x (times). The RRB buffer output impedance is set a little lower than the Dc resistance of a standard guitar pickup to equalize the effect of following load impedance. Input impedance is set at 500K for a medium load to standard guitar pickups. This keeps the tone and guitar volume taper natural.
SETTINGS
TREBLE BOOST: Set Boost to minimum and Master to maximum and adjust for a desired treble boost with the Treble knob. STRAIGHT BOOST: Set Treble to minimum and Master to maximum and adjust Boost to the desired effect. BOOST: The gain of the booster and can be set from unity to about 40dB of boost. When this control is cranked the unit will distort within itself. DISTORTION: Set Boost to maximum and adjust output level with Master to unity, then adjust Boost for desired depth and overdrive. Treble can be used to enhance distortion effect. CAUTION ! Never operate the unit with its bottom removed or damage will most likely occur.

💜
my 6’4” husband wore this to our wedding. it looked amazing on him 💜 everything fit pretty good except for the jacket part; that was a little big. it may fit someone who weighs a little more but my husband weighs about 165lbs. we had to tailor it a little bit. other than that, very beautiful suit.

Impressive Quality and Style – A Perfect Prom Look!
Size: Small, Color: Maroon Collar Black
I purchased the YND Men's 3-Piece Slim Fit Tuxedo Suit Set for my son's prom, and I couldn’t be more thrilled with the results. From the moment he put it on, it was clear this suit was something special. The fit was absolutely sharp and flattering, perfectly hugging the frame without being too tight — just the right balance of tailored and comfortable. The material feels high-quality and looks even better in person — smooth, sleek, and polished. It held its shape beautifully throughout the night and gave my son a sophisticated, modern look that turned heads and earned him plenty of compliments. You can tell this suit is well-made with great attention to detail, from the stitching to the lining. It easily rivals much more expensive brands. I’m so impressed with the value and style that I’ll definitely be purchasing from this company again. If you're looking for a tuxedo that delivers elegance, confidence, and exceptional quality without breaking the bank — this is the one!

A Good Value
Size: Small, Color: Black, Size: Small, Color: Black
The suit is a good value. Ordered for senior prom for my son. He is 5’10 athletic build and between 165-170 lbs so we ordered the small since he wanted a slim fit and nothing that would be very loose. The suit fit him great, not too snug , the jacket has a satin finish on the lapel and edge of pockets which gives it an elevated elegant look. The jacket has an interior pocket but the rest are just for aesthetic as they do not open. I did have to cut a small slit in order to use the pocket square. The pants fit like a glove but you may want to size up if you are very muscular. The material is light weight which is perfect for prom season or warmer weather. The vest was oversized but we were not planning to use the vest anyway. Quality: several hanging threads that needed to be snipped but no big deal, the stitching was even and straight and the interior had piping of a complimentary fabric. After a full night of dancing and activities he did not have any issues with stitching breaking or splitting of seams. The buttons are black with a silver edge which give the suit some sophisticated flair but keep this in mind if you plan to style with gold. Overall, I am very pleased with this suit considering it’s price point. It’s perfect for a teen that will attend various senior events. Shipping took 2 weeks so plan accordingly and pay attention to the expected delivery date.
