I'm thinking about replacing my delay & modulation effects and going with multi effects processor. I've been checking out Zoom G3 and host of others (line 6 HD series, Digitech RP1000, Vox ex) . What I'm looking for is the ability to bypass amp simulations to and basically use the unit for delay,reverb and looper. I'm planing on just using amp simulations for late night jamming with set headphones but also I want to be able to incorporate my two favorite dirt boxes. I'm big fan of M9 I've been checking out HD 400 I just want the ability to bypass the amp sims.
