As a headphone amp the Spectradrive works just fine, its better than my Elf and it also has the Aux in, which is very useful if you are learning covers. I bought this during the lockdown, I was at home, practising for several hours per day but wanting to stay on good terms with the neighbours (I thought my Elf's headphone out was faulty and it was about to be sent off for repair). The B1-4 was sold out everywhere, even Thomann ran out and I didn't want to wait a month or more for new stock to arrive so I thought I would buy the spectradrive and possibly make use of its pre-amp/DI facilities too. Both bits of kit are good value but the Zoom does a lot for very little dosh.
Glam rock!😀 I suppose @javi_bassist's pedal board is a bit glam rockish, I am guessing Javi doesn't play in a death metal band😀. The colours are really nice though.
