Hey guys, I am pairing down again after a binge on gear and basses. The Carvin B1500 is truly an amazing amp. Built in the USA, insane amount of power, thump and clarity, just a real work horse. $400 shipped CONUS FIRM specs from Carvin: The B1500 mono block bass head offers classic natural bass tone with the high- est power headroom available in any bass amp to date. The B1500 delivers 700w at 8Ω, 1250w at 4Ω and 1900w at 2Ω. The B500 bulges with the same huge tone but delivers 225w at 8 ohms, 350w at 4Ω and 500w at 2Ω. Four discrete Class A input stages produce the harmonic basis for the preamp right from the input jack. It begins with a boutique flat response, then we add 6 tone controls for you to carve out your signature sound. Harmonic content increases as you turn up the Drive control producing a growl at maximum settings. Solid design, bullet-proof construction and a list of indispensable features assure the B500 or B1500 will be the heart of your rig for years to come. Discrete Class A input stages Active/Passive input gain switch with input CLIP indicator Preamp DRIVE and master VOLUME controls Six EQ controls: SUB BASS, BASS, LOW MID, MID, HIGH MID, and TREBLE Signal MUTE front panel switch (also controlled by optional FS22 footswitch) EFFECT LOOP front panel bypass switch (also controlled by optional FS22 footswitch) DIRECT OUT balanced XLR with independent LEVEL control, switchable "Pre-Post" and "Ground Lift", DC isolated TUNER output jack independent of MUTE switch Internal OPTO (optical isolation) clip-activated power amp limiter with limiter free normal operation High current SPEAKON® connectors and 1/4 speaker jacks Metal shaft controls with threaded metal bushings mounted directly to front panel 19" 3U all steel chassis Trade wise, I might be game for a Mesa Boogie m9 plus cash from me or something else that might try to dethrone my Fathom/m6 that I love so dearly.
