This is the reason: it is BOSS.
Then a tough one to rate. Why?
A bell rang, with the real reasons: A small room. A smaller place to practise. A need of all FXs. But where?
How do I put my DIY wood board, where to toss in the trunck my mix of BOSS, mxs, screams for Pepa, badass drives, the tuner, and my girlfriend´s speaker for the summer winter easter holidays?
I am not saying that this is a must for travellers, but it is one good reason.
Ah! Add the price of 30 BOSS pedals + power supply (either 9v batteries or a MULTI charger + pedals connectors) and compare.
Seriously. A 30cmx18cmx"3 finger-height" box with all of the above.
Put it in your travel suitcase man, because the board and your pedals stay at home...
Enough reason?
