Hi there. We had a mini-gathering of bassists chez Wulf (Lewisham, UK) on Saturday. The main aim of the meeting was actually for me to pick up my new Epifani UL110 from Matthew Foote. Thanks Matthew, great cab! Anyhoo, while we were there we decided to A/B my new Acoustic Image Clarus series 2 against Matthew's older series 1. Big deal, I here you cry, the only difference is that series 2 comes in a larger box and has the notch filter. That's what I thought as well... Read on... We played both through Matthew's 2x Accugroove Tri112 rig and had another (different) Matthew play a groove on his Fender MIA Jazz. With identical settings on both amps, mine nudged ahead of Matthew's Series 1 Clarus in terms of "headroom". I won't say volume per se although it did sound a smidge louder, but there was definitely a difference. Isn't that weird? Anyone know why this might be the case? Oh, and while we're here, the Clarus through the Epi UL110 is just AWESOME. I must confess there was definitely a BWAH-HA-HA "voice of doom" moment when I first plugged it in. AND it's super-portable. Me likes!!!
