I play normally Heavy Metal, Progressive and Blues. I am pretty satisfied with distortion and lead/solo sounds I got using the Equalizer settings on my Boss ME25 Unit but, as far as clean sounds are concerned I cannot seem to adjust them on my Boss unit. Sometimes clean sound with delay/reverb for example sounds a bit distorted with the amp i am using now.

I would like to connect my Boss ME 25 processor to an Amp, the Amp I am using now is pretty old and I can't seem to make the right decision regarding a new one. Would any Amp do? Like Fender Champion 20 or so?

The issue you've described boils down to gain, ultimately. You can set your Boss ME25 to produce a nice clean tone, but if the output volume is too high then it will still distort the preamp section of your amplifier. To get a totally clean tone, I would reduce the output volume of the ME25 and turn your amp up.

Having said that, you've not stated what amplifier you are using. A small tube amp will begin to 'break up' and distort unless you are careful, so I would look for an amp with a bit of clean headroom. It might ultimately be best to try a few out with your ME25. Given your mention of Fender's Champion 20 amp, I would guess you are after an affordable practice amplifier, of which there are many.

  • Thanks for the feedback! I am using a 30W GX-30 Transistor based Amp. I tried what you suggested, there's a Volume knob and a Gain knob for clean channel, Gain was already set to low, I changed the EQ settings on Amp a bit and it seemed like there was a slight change. – Abel Tom Apr 25 '17 at 16:48
  • are you boosting frequencies with EQ on the Boss or attenuating them? raising them above 0 = gain. If so, try resetting your boss EQ by moving "the curve" down from zero. (i.e. if you have 3-band eq: +5;0;+3, make them 0; -5; -2) – Yorik Apr 25 '17 at 20:14
  • You should be setting the gain lower, and then boosting the volume. If you need to boost the fain for whatever reason (I don't have a GX-30) then the output should be set low on the Boss effects unit. – ABragg Apr 26 '17 at 13:05
  • @ABragg Yes, I tried increasing the Gain on the Amp and reducing the output volume on Boss to 50, previously set to 99, sounds much better! – Abel Tom May 1 '17 at 5:34
  • @Yorik I have not used EQ settings on my Boss unit, the three knobs usually used are Drive, Tone and Volume. – Abel Tom May 1 '17 at 5:36
