| Yeah, the vast majority of amps are "clean" if you don't push them hard. Try turning down. Not loud enough? Get more speakers. If that's not loud enough, then keep the more speakers and replace the amp with a more powerful amp. Again, brand and model is nearly irrelevant- the key is to have enough volume before distortion, which has more to do with the speaker surface area and the power of the amp than it does the "type" or brand of amp.
For a clean DI, use the Google search TB function here, in the Amps forum, in the Live Sound forum, and in the Misc. forum to search on "DI" or "best DI" or "clean DI" etc. Thousands and thousands of threads on the subject. |
