So - if you have an old BOSS ME-5 - Don't sell it!
Few people realise that the ME-5 incorporates the classic BOSS pedal internals that are now vintage in their own right including the:
CS-2, DS-1, OD-2, RV-3, EQ-1, CE-2, DD-2, BF-2
all together with a switchable Noise Suppressor that calms the proceedings. I have an all up-to-ate set of BOUTIQUE Patches in mine that gives me classic sounds such as:
Univibe, Vibratone and other Leslie effects, Rangemaster, Fuzz-Face, Tweed and driven Deluxe Reverb emulations, classic JTM45, Rockabilly, Bluesbreaker, 'Rectified' and 'Twang' - all classic tones in various states - and not modelled!!
You can get a set too and upload either via sysex/midi and your PC or manual input - CLICK link where to get them
