Vintage Pow - Colorsound Overdriver / Power Boost

Hot! Vintage Pow - Colorsound Overdriver / Power Boost

A hunka hunka burning vintage overdrive tone right here.

The Power Boost was one of the major components of Gilmour's sound around DSOTM, with luscious, rich overdrive on just the right side of saturation overload.

This kit offers the choice of making the Power Boost, which likes 18V or the Overdriver, which runs at 9V. They both sound great, but the Power Boost has a lot more headroom to play with, so you get more oomph with less clipping.

Both versions can be built with either BC169C or BC109 transistors, but opinion around here is the PB is best with 169, OD with 109. The board has been designed so you can use either without any leg twisting, despite their different pinouts. BC169C are available in very limited numbers. When they're gone, they're gone.

There's an optional on-board charge pump so you can get your 18V from your standard 9V supply. Result!

Designed for vertical-mount pots (which have round shafts - you'll need knobs with set-screw fitting), but you can wire in 'normal' pots if you prefer.

Yes, there are pads on there to take two different switches. The bottom SPDT is to select between 9 or 18V if you have the charge pump installed. To be honest the PB doesn't sound right at 9V, and the OD doesn't sound right at 9V, so its best to hardwire the circuit for one voltage. The DPDT at the top switches a few component connections. The idea was you could switch between PB or OD circuits, but it must have been a late night when the idea came about - there are component value changes between the two circuits as well as those two sets of connections. Leave it alone. Make one or the other.

Brilliant! Not your usual... 5 product stars
"This is a great pedal. Not your usual boring boost/ OD - it can push your amp or another pedal really well, give you a treble, bass and/or big level boost for solos, and has a great natural sounding OD when cranked. It's almost more like power stage distortion than preamp. I've built a couple of these now, as well as a few BYOC's over the years. Fuzz Dog kits are cheaper and have more options than BYOC. They are great kits and I am happy to recommend them to beginners or pros. Love 'em." Tim O - 04/09/2015
Power Boost Clone 5 product stars
"being a Gilmour fan, I've been building my rig around those tones and obviously a Power boost was on the cards. However, I'm on a tight budget, and happened across this clone kit when Googling. I had never built a kit before, my soldering skills are ok, but not the best, however I decided to take the plunge and buy the kit. I opted for the power boost variant running on 2 9v batteries. I was also going to install the adaptor socket as I want the flexibility of running the pedal in my rack, or stand alone through a combo for smaller gigs. So far I haven't been disappointed.... It went together easily, I checked and over checked twice before soldering anything, and the end result has been a revelation.... The tonal qualities are excellent, and the gain is good, however the boost in volume is colossal, good job this has a volume control (The originals didn't) so you can tame the beast. It will rattle windows." Andy Betts - 22/09/2014
Fantastic! 5 product stars
"Sounds absolutely amazing! Member of a Gilmour forum and the guys there are amazed at how good this sounds - they know their stuff! Love love love this pedal!" Phil R - 22/08/2013
Excellent kit. 5 product stars
"The PCB is excellent, high quality. Fits easily in the enclosure leaving space for a charge pump if you are building the P.Boost. The build is relatively easy and the instructions are more than clear. I had some questions - they were answered in a friendly and understandable manner." Ian - 03/08/2013
Vintage POW! 4 product stars
"This kit/pedal is just great! Simply great! My plan was to go for the "original" 18v Power Boost rather than the 9v slightly different circuit Overdriver. I used thePB trannies and circuit but so far have only run it on 9v. Put it together (quickly ... in a hotel room in the Hauge!) checked and it worked first time. Boxed it up and it still worked (this is incredible for me!). Now why do I like it so much ? It's not for the overdrive ... not the distortion (although great) but for the range of tones. It is a Baxendall tone circuit after all. My modded Epi Valve Junior clone doesn't have the greatest range of tone control, but this gives it to you. And with the extra umph! the pre-amp value just gets pushed over the edge for crunchy goodness. So, it's not a clean boost, it can be a treble boost, it can be a bass boost, it can be a mids boost, it does overdrive and it does distort ... just love it!" Jonathan Dean - 08/04/2013
