Bluesbreaker sounds/pics

I finally got to put the BluesBreaker clone into an old HD cabinet. Mostly for fun, but also because it's a very good housing and easy to mount on my pedalboard (and who needs a slow 210 MB HD?)

I have put a few pics and a new MP3 soundclip on my HP www.radmer.dk for you to enjoy.

I like the sound of it very much. It's full and open with enough gain for blues. Please consider making one if you like this kind of sound.

I've been really happy with the bluesbreaker that I built for my father. My only change was a tl082 vs the tl072 opamp,.. the most amplike and un-pedal-like overdrive I've used yet. Actualy got mine dead quiet in a plastic chassis, not as cool as your harddrive case, tho!!!
A trick for shielding in a plastic case-- use shielded leads to your pots, jacks and switches, wrap the pcb in thin foam, and inside the foam I took a piece of printer paper, big enough to wrap the pcb in, with an equal sized piece of aluminum foil, put a lot of glue-tape on the paper, laid a piece of hookup wire that had been stripped all over the gluetape, and put the foil on top of it, very solid connection. attached the drain to a good ground point, and wrapped the pcb, paper side toward the board of course, then wrapped the whole thing in foam... as quiet as a metal case at a fracoin of the cost!

Re: Bluesbreaker sounds/pics

Which schematic did you use? I have seen
two which differ slightly-- connected to
the inverting input of the first opamp
there are 2 resistors, in one diagram
4k7 and 3k3, in another, 27k and 33k.

Are these two versions of the pedal? Or
is one of them simply wrong? It appears
they would give different gain by a factor of
about 10 (at high frequencies at least), and a different frequency response.

Lou	Jim, I put a Rat clone in a Gandolf (5242i) ISDN modem case. a little big but it was free...Just for laugh's..

Gustav	That schematic is prob from me. values were from two diff BBs, they were traced out 6 months apart so I can not tell you how differnt they were I would build the one with 4k7 and 3k3 for more gain.

Jim Radmer	I built from Frank Clarke'es schematic at: http://members.home.net/fclarke/fx/ Without including the extra switches. I think I will check those two resistors again because it does not have that much gain. My new BB2 has a lot more gain I tell you.

Eric H	Sounds great, Jim, that's a pretty cool riff, too. -Eric
