Just got to play my new Thunderfunk amp (*) with my funk band last night and it kicked major booootaaayy. Strong tone, and plenty loud. My funk band is a fairly loud band (loud drummer) so it takes a lot of umph to keep up. The Thunderfunk had no problems. I was at about 5 on the volume scale and was plenty loud. I also noticed that for really the first time ever I could really hear myself when I stood close to my amp. I used to use 1600W but this has no problems with loudness or headroom (it is a very clean tone) The light weight of this amp is great (my former rack weighed around 65 pounds and was a pain to move around). I agree with everyone else that the Thunderfunk sounds good just set with the EQ flat. I did boost the lows a little (but I like low heavy tone). The Timbre control is very powerful and can make your bass sound like a deep dubby style bass or almost guitar-like. The EQ does show everything in your playing as it is very even across the tonal spectrum. The mids show up more than I have ever had in another amp, yet it is not "farty" sounding. Dave Funk has got a good product and I highly recommend it. The rest of my band (especially my drummer) really liked my tone. *Oh yeah, did I forget to mention: TFB550 !!!!! aka: 500W custom prototype pro-model & 2 preamp tones through a new magic switch on the front of the amp . 1 way is classic warm/rich Thunderfunk tone and the other is a clean clearer tone. I did pay a premium/higher price for this, but it was worth it.
