Hi everybody there:
Since last year that i donĀ“t write any post, so happy new year. I back again, and have some to tell you.
Following my "roadmap", i already maded a Ruby with a tone control big muffed style with pretty success. (Coihue Micro). I had learned that for my, about 50% of the sound is the speaker. After, i used the ruby like a "test amp stage" for severals pre. I tryed ROG thor, thunderchief, and tonemender, with some succes just with the tonecontrol. The others, well, :grr Reading the forum, that circuits, no work at all, so, i put them a side.
Then, i made a TDA2005 datasheet BRIDGE power stage using a power supply maded with a rectifier bridge and a dicroic feed tranny. (about 50VA) It work pretty nice, using just a buffer stage with a MPF102 direct from the guitar, and i sound very nice, clean. Regrettably, in that time just have a cheap 6" speaker, so it sound like sh... when i hit hard the strings.
Since about two weeks, i purchased a 12" - 8 ohms speakers at J M FAHEY and with it, is a peace of cake <3).
I used like preamp, then, a Marshall BluesBraker clon, mounted over a perfboard, and it works no so good, (when it worked).
I planing to etch a board of that Marshall BluesBraker, then see what append. I looking for a versatile circuit of a preamp, that gimme a "marshall-like" sound, (going from nice clean, to medium distortion, Hells Bells?, you know?) with a good tone control, and foot swicheable distortion, and a effect loop.
I founded the circuit of a Trace Elliot SuperTramp, and looks pretty nice, but, no idea that what FET them uses...
Any suggestion about a circuit?
Founded a good pre, next step is make a TDA7294 power stage.
