This is not "new" info. But I have to say it again as this is months past any "honeymoon" stage or comments.
THE GAIN CHANGER IS INCREDIBLE! There, I said it. Pedal was so well thought out that the only things I wish I could add could only be accomplished with a bigger box/more controls. The mids switch. SUPERB! And thank God David decided late in the game to include the small mid bump to the mix, as I use it MOST of the time with humbuckers. The LTD/UnLTD switch. Again, superb. This thing can be as sweet and smooth as my LTDv2 and it can be pretty mean too. But, ALWAYS retaining the sound of your amp!
This is a FABULOUS solo boost pedal as the mids switch, tone knob as variety of gain available for solos can be anything from subtle boost, small gain boost, small level increase, small mids hump to what I used it for last week... I had to switch from clean rhythm tone with my Tokai strat, to singing lead sustain.
Lastly, this pedal does all these things whether hitting your favorite amp as the base tone, OR when stacking with other pedals. I just retubed my Tweaker and it sounds better than ever. Last night I had Tokai Strat (I am authorized reseller of new MIJ Tokai strats and tele's by the way) >Tone Press>Gain Changer> Compact Direct Drive> Tweaker on fender settings. I was leaving the CDD on in low gain mode as my base tone. Doing clean solos with the TP and smooth singing solos with the GC in LTD mode and really singing solos with GC and TP kicked on. I know the Tweaker is not a high end amp, but I'm telling you that the tones I was getting last night with this combo were glorious! Oh, I forgot one thing but those of you who have read my posts for the last 10 years already know this. The Launch Pad was last, on all the time AS ALWAYS with every setup, amp, guitar and pedal chain I use. It's ALWAYS on.
But this thread is about the Gain Changer. To summerize: GAIN CHANGER RULES!
