I can't specifically remember which or where it was... found it a couple three weeks ago. He was talking about the differences in the preamp section of the 2205 & 2210... that aside from minor tweaks the only major revision was done in '86 or '87 and to find out which version you have... pull V2. Either one channel stops working (boost!) or both stop on the later revisions... Most/all of the changes addressed the known "channel bleeding" issues of normal being audible even while boost is selected...
Well...
I have an '84 2205, so it should be first version. I've had it modified but that was all contained to the boost channel, removed the diode clipping & made some changes to the tone stack, EQ voicings... other then that the amp is bone stock. Always defaults to the boost channel, you can't even get 'normal' w/o a footswitch which I haven't had for eons... I always got around the channel bleed thing by using the 2205 as a single channel amp & turning all the 'normal' channel knobs to "off" position. The 800 has always sounded "good" too... not my favorite amp but I didn't buy it for me really!
So late last night, for the halibut I decided to pull V2... just so I could hear the boost channel "not work" and confirm which revision of the preamp circuit was in my amp...
Well... I was shocked...
astounded...
totally flummoxed...
Blown away!!!
Took the amp out of standby and the boost channel kept going...
But not only did it keep going... but the amp sounded A MILLION TIMES better too!!! Remove a tube and get MORE tone??? How's that work?!?
With V2 removed the normal channel is deactivated entirely... no more channel bleeding. Even though I had the knobs set to "off" apparently there was still quite an effect on the boost!!!
Amp got louder... clearer... bigger... smoother... sustained longer...
Not a subtle difference!!! Amazing... totally amazing...
I kept replacing & pulling V2 just to confirm that yes... I was hearing & feeling an audible difference and there was! Even more so, the differences between tubes in V1 are MUCH more pronoucned! Put in an Ei or JJ, Amperx, Brimar etc. and the differences in tone and gain are just way more obvious without V2 in the way!!!
Completely shocking...
