The head is in excellent working order. It has minor rack rash, some scrapes on knobs, and is missing a couple of screws on top, but that's about all the wear and tear I can report. Price - $750 including the effects bypass foot switch, if you can pick it up in Juno Beach FL; otherwise, for $800 I'll FedEx it to you anywhere in CONUS. Note - this amp is not the Mini-Mo' preamp Sorry - I don't have actual photos to post and the head is on consignment at a music shop 1/2 hour away, so I can't easily take any; but the description is accurate. For those that don't know what this head looks like though, I'm including a stock SWR photo. Although this comes with a standard Chinese 12AX7/7025 tube, I have many wonderful fully-tested vintage English, German and Dutch replacement 12AX7/ECC83 NOS tubes for sale from $60 - $160 additional; if you want to upgrade it. There are subtle tonal differences with these tubes in this head, particularly in the details of the built-in effects; and well worth their price IMO. For those who are unfamiliar with this amp, here's excerpts from SWR's manual, which describes it head very well: Possibly the only multi-effects unit tailored for bass, incorporating all studio-quality ANALOG modules. The Tube Overdrive is not of this earth. The Octave Effect (he called it a "SubWave") tracks notes in registers so low it seemed impossible. The EQ circuit is a thing of beauty, and the Chorus simply sings. By the time you hear the Synth pumping out sounds straight off of Stevie Wonder's "Songs In The Key Of Life" album, you know you love this head. Now you can own a single amplifier that can be as simple or complex as you need it to be. Run it totally clean into one speaker cabinet for classic SWR sound. Run it into two cabinets and use the chorus. Split your clean and dirty signals using the Dual Mode feature. Combine effects. Switch back and forth. Experiment to your heart's content. Use it in the studio with everything on at once for sounds never before recorded. Send one signal to a mixing board. Send two. Send three! â€¢ Dual independent input jacks compatible with both passive and active instruments â€¢ Pre-Amp Volume Control with bi-color (green/red) LED peak clipping indicator â€¢ Variable Limiter/Leveler Control with yellow LED indicator â€¢ Aural Enhancer Control â€¢ Treble Level Control â€¢ Midrange Level Control â€¢ Midrange Frequency Control â€¢ Bass Level Control â€¢ Overdrive "Drive" Control â€¢ Overdrive Level Control â€¢ Subwave Tone Control â€¢ Subwave Mix Control â€¢ Bassynth Filter Control â€¢ Bassynth Resonance Control â€¢ Bassynth Envelope Control â€¢ Bassynth Mix Control â€¢ Mo' EQ Treble Control â€¢ Mo' EQ Midrange Control â€¢ Mo' EQ Bass Control â€¢ Chorus Depth Control â€¢ Chorus Rate Control â€¢ Push switches and unique-colored LED indicators for on/off control of all effects â€¢ Internal Effects Bypass Switch with LED indicator â€¢ Left and Right External Effects Blend Controls â€¢ Dual Mode Switch with LED indicator â€¢ Left and Right Master Volume Controls â€¢ Illuminated Neon Power On/Off Switch â€¢ Stereo Headphones Jack â€¢ Screwholes for Rack Mounting (on chassis in each corner) MO' BASS REAR PANEL FEATURES â€¢ Direct Out 1/4" jack â€¢ Tuner Out 1/4" jack â€¢ Mo' Bass Out 1/4" jack â€¢ Direct Out XLR jack â€¢ Mo' Bass Out XLR jack â€¢ Line/Direct Switch for 1/4" and XLR Direct Out Jacks â€¢ Individual 3-position Pad Switches (0 dB, -10 dB, -20 dB) for both Direct Out and Mo' Bass Out XLR jacks â€¢ Ground/Lift Switch for both Direct Out and Mo' Bass Out XLR jacks â€¢ Stereo Effects Loop (Left and Right Send and Return 1/4" jacks) â€¢ Internal Effects Bypass Footswitch jack â€¢ Filter Sweep Pedal jack â€¢ "Mo' Control" Footswitch jack (shown as "Ft.
