Hi Friend, I hope your week is going great! I just wanted to send you a quick update on Indyguitarist.com and Guitartone.net websites. In effort to bring true tonal joy to even more of the masses (and due to customer requests;) ) you can now download the "How to Build Effects" book: http://www.indyguitarist.com/1105-memberpricing.htm I will soon be offering mods on some rack preamps. A few of the ones I've been developing are mods for the ADA mp-1, the tube works tube driver, and the marshall preamps. Here are some soundclips so far: Marshall "9004" solid state: http://www.indyguitarist.com/soundclips2/marshall%209004%20ss%20preamp%20w%20mod.mp3 ADA-mp-1: http://www.indyguitarist.com/soundclips2/back-in-black-ada_mod.mp3 http://www.indyguitarist.com/soundclips2/3steps-ada_mod.mp3 http://www.indyguitarist.com/soundclips2/zztop-ada_mod.mp3 I believe mod prices for preamps will run from $150-$300 depending on the unit. We are also working on some amplifier modifications as well -- either tube or solid state. We have a new poll up now! Please take a minute and vote!
