My Sunn Concert bass used for guitar

[nickdrone]

Is way more awesome than when I use it for bass. Absolutely loves a fuzz and 4x12 cab. Sounds very awesome through the sunn 215bh I have to match the head as well. It's the red knob version (150 watts@4ohms) and I run it through an 8 ohm cabinet(the 4x12), so it's still pretty incredible for being run at a lower wattage.

Anybody know how close the Concert Bass and Concert Lead heads are sound/schematic wise?
I know the Concert bass is an "all range" amplifier, so is it possible the Concert Lead is the same base circuit with added distortion channel and reverb? I was debating picking up a Concert Lead but if they are almost identical then there'd be no point in doing so.

Thanks! -nick

The power amps are the same. The preamps are similar, but I'm not sure if the eq frequencies are the same.

Alright thanks Isaac, that definitely helps. If anyone else has knowledge on the subject, let me know.

I can't find a Concert Lead schematic to compare to the Concert Bass.
