Comments about TECHNICAL PRO SLIMPROB1200 - 1200 Watt Amplifier:
I use this as a power amp in my guitar rack to power my Marshall JMP1. I needed a 1U amp that provided a bunch of power. This is the only amp I found when you compare power vs. cost. However, if I had the money (and a roadie) I would have bought a different amp (2U). Though Techpro has made some improvements (ie. it actually now fits in a 1U once you take the rubber feet off), the cooling fan is really noisy, and it makes more white noise than I would like. It's not intolerable, and definitely not noticeable during live performances, which is what I use this for. Also, the operators manual is incomplete. It would have been helpful to have power specs on the differences between Parallel and Stereo mode and recommended connections.
I would not use this for recording.
