I have owned the 4100 since 92 and had her ressurected recently (replaced bad 50/100 switch and retubed). Wow, does this thing move air! I got a great deal on an Avatar 412 and it really has some potential. Recently I found a pair of MXR 108s for $50 each at GC and I plunked down on one (considering buying the other as well for an eq for each channel). I'd love to hear what you have learned about yours, and was actually thinking of starting a thread once the 30 hold ran out on the MXR(s) and I took it/them home. Do you have some favored tone settings? Do you use an eq?
