I'm looking for a pedal to "warm up" tone for a few songs. SWR amp is perfect for 90% of the set but could use: warmth, harmonic enrichment, other meaningless description here_____. Not distorion or overdrive; more like an SVT CL set clean; it's not just roll off the treble but thicker in a non-EQ way. Seems like One Control Silver Peg, or Green Hooker, maybe Linden pedal could work??? I had a Blue Tube years ago that I didn't care for but also didn't spend a ton of time with. Is there a difference between the Blue and Real pedals, and, would either one be a good choice? Is this reqest unreasonable without trying them in person?
