If I was to get a DI box, do you have to spend crazy money or would something as basic as the Behringer D120 suffice ? I assume it's located as the last thing in the signal chain before you go into the mixer ?
What difference will it make to the sound - will I be back to the sound I had prior to getting the TU-3 or will it be more of the same in the sense of a truer (in my case bad) tone ?
Are you able to clarify what you mean by the 'buffer' in the pedal ? I've always thought of the TU-3 (and the TU-2 before it) as something of an industry standard and I wouldn't class it as particularly cheap, I'm surprised it doesn't have the bypass circuitry you talk of.
Many thanks for your time.
