My main rig for the past 3 yrs has been a SVP-Pro->PLX1202->Whappo Jr. Today a brand new Epi UL310 came UPS. I hooked it up to my main rig and plugged in my fav bass (ATK305) and spent about 1/2 hr playing. This cab is about the same size as a single 15 and weighs 47 lbs. It has 3 neo 10s and a small tweater with a Lpad in the back. The tone is clear and clean without any humpy bumpy response characteristics. Not as thick and big as the Whappo Jr. but definately big enough and at about 1/2 the size and 23 lbs. lighter. It responds to EQ PUP changes on both and guitar and pre-amp. With the pup selector set in the middle and the pre-amp set flat I can get an outstanding slap tone. With the pup selector towards the neck and the treble on the bass rolled off a bit you get an outstanding fingerstyle tone. I pulled the trigger on a Shuttle 6.0 last night on ebay and am looking forward to gigging with both of these new pieces of gear.
