Boss RV-200 Reverb Effect Pedal

You can get just about any reverb effect that you desire with this little box - and then save it in memory. You can set the number of memories you want so that you're not toggling through all 128 to get to your sound, this means it is very practical to use live.
Plenty of in-depth demos on Youtube but when you actually get this pedal you realise it's a good, solid box and after a few hours of discovering those perfect sounds for you, you wonder how you got by without it.
Having the same footprint as the other Boss 200 series pedals is the winner for me. All those sounds available in one small easy to use box is incredible.
