BOSS
ACA to PSA Power Supply Mod (PSA) The older BOSS pedals may not work correctly with a modern AC power adapter (like a 1-Spot or BOSS PSA). These older pedals required the BOSS ACA adapter and they have a sticker on the housing right next to the power supply jack. The ACA supplied a higher voltage than the PSA. The ACA voltage is unregulated and the PSA supplies a regulated voltage. The PSA Mod allows your ACA pedal to accept modern and the BOSS PSA power supply. $29 for the mod alone or add $20 to the price of one of the below mods.


BD-2 Blues Driver (Fhat) The BOSS BD-2 is one of the best overdrive pedals BOSS has ever come out with. The MCKINLEY BOSS BD-2 FHAT MOD comes from years of experience to develop an upgraded circuit with improved warmth, smooth midrange, clearer highs, more responsive with better articulation and full frequency response yet transparent. Its musical, tube tube like asymmetrical clipping pushes your amp while keeping its tone! At high gain, it gives you a gritter, edgy tone. Engage its FHAT Switch for a slight bass increase. Due to the extent of this mod, its price is $69.

BD-2 Blues Driver (Brent Mason) To help you sound like top Nashville session super picker, the MCKINLEY BOSS BD-2 BRENT MASON MOD gives you a fuller, more rounded sound which shines at low to middle gain settings.  

BD-2 Blues Driver (Tweed) For more of the those coveted woolly tones from the vintage Tweed era, the MCKINLEY TWEED MOD with get you that tone without the four figure price for a Tweed amp.

With increased touch sensitivity the Main Squeeze places singing leads and instant feedback at your fingertips. Your amp will sound richer, warmer, and more spacious. Great as a compressor or a volume boost!  A bright yellow LED replaces the BOSS red one. For MIJ models, like the CS-2, it breathes new life into them!

CS-3 Compressor (NOS Tube) Vintage vibe and mojo! In the spirit of the Fairchild 660 and Altec 436 tube compressors, as they were the "secret weapons" of the Beatles engineers at Abbey Road in the 60's, the NOS Tube helps to capture the coveted subtle tube compression, organic feel and open air of these legendary compressors. Its use of germanium diodes and circuit upgrades create the tube like fluid compression for use on acoustic and electric guitars, vocals or drums for the vintage organic sound. The NOS Tube just keeps "getting better all the time".

Big Muff Pi Fuzz - black, russian version - (QOSA) Brings back mids for a BIG, FULL sound for a QUEENS OF the STONE AGE type of tone. The distortion can also be modified for more of a creamier or high gain sound (one or the other, not both). Please specify if you want this change made.
