Amps I've owned:
Nomad 55 1x12 7/10 -- I found the voice to be too modern
Rectoverb combo 8.5/10 -- Great tones, but a bit narrow
Mark IIC 9/10 -- Incredible tone and feel for rhythm; shared controls
Mark IIC+ 9/10 -- Incredible tone and feel for anything; temperamental; a bit too edgy to be THE amp for me; shared controls
Mark IV 9.5/10 -- Versatile and reliable, but loses the vintage feel of a Mark II
Amps I've demo'd
Lonestar Classic (1x12, 2x12) -- 9/10
Lonestar Classic (4x10) -- 9.5/10 Possibly the best single sound I've heard from any Boogie
Lonestar Special (1x12) -- 8.5/10
Dual Rectifier 8.5/10 -- Not my cup of tea; not articulate enough
Stiletto Ace 8/10 -- Not my cup of tea
Express series 8/10 -- Not my cup of tea
Studio 22+ 9/10 -- Borrowed one at a recent party; pleasantly surprised; Mark feel without the weight!
