I am downsizing from an iAmp 800 to something that really only needs to be loud enough for practicing. At some point I'll get a 110 or 112 to go with it, but I will not be trying to power anything bigger than that. I would like to keep it portable so that I can throw it in the pocket of a gig bag to use as a practice amp with headphones if I'm traveling. I'm looking for opinions on some of the lower power mini heads that are floating around out there. Even though I'm not going to be playing loud, I still want it to have a nice clear tone. Here is what I am looking at: SWR Electric Blue Markbass LM 250 EA Micro 300 Eden WTX-260 Genz Benz Shuttle 3.0 Epifani Epifunky 300 Something in the neighbourhood of 150W @ 8 ohms/300W @ 4 ohms will be plenty. If it's got the tone I can make due with less. An aux. input (or some other way of getting recorded music into the headphones with the bass) is a definite plus. It would also be nice if it didn't have a cooling fan, but I don't think a micro without a fan exists (yet). I have owned a LMII and I assume that the LM 250 sounds the same. It doesn't have aux. inputs and they don't pop up on the used market very often. I have also owned a Shuttle 6.0. I liked it, but I'm not sure how different the 3.0 sounds as it doesn't have the tube in there. I've read a lot on the EA Micro 300 and the Eden WTX-260. Both have mixed reviews. Most agree that they sound good, but are under powered, but under powered compared to what? Compared to the other higher powered micro heads that are available or compared to other amps that have similar power ratings? Does anyone out there have enough experience with these little guys that they could help shed a little light on the tonal differences between them? Edit: Part of the decision to look at these amps is price driven as well. If I could find a higher power head that had all the features I need for a killer price I wouldn't let the fact that it has more power than I need stand in the way of a good deal.
