Yeah, the Zoom B3n or B1-Four (much cheaper). No DI but other than that, does all the Spectradrive does and way more. For home practice you have amp and cab sims, headphone out, aux in, looper, drum machine, loads of effects etc.
Dont get me wrong, i love the Spectradrive, but I find its a very basic box, albeit one that covered my needs at the time. Killer feature for me has always been the EQ. Its just perfect for my tones. I got a BH800 head based on it having the same EQ section.
