Mesa Boogie Quad preamp 1989

Mesa/Boogie Quad Preamp – classic rack tube preamp (2U) w/ Graphic EQ + Reverb

For sale is my Mesa/Boogie Quad Preamp in very good condition, fully functional and ready to rack up and play.

This is the famous dual-channel “Mark-style” rack preamp with two fully independent channels, each with its own 5-band Graphic EQ, plus built-in reverb and stereo outputs (A/B).

The preamp is fitted with brand-new premium Genalex Gold Lion 12AX7 / ECC83 (gold-pin) tubes, as shown in the photos.

These are high-end, great-sounding tubes (not cheap stock replacements) and they contribute to a very rich, detailed tone with excellent headroom and definition.

• Original Mesa footswitch is NOT included.
• In my demo video I use an RP93 MIDI switcher to change channels / modes remotely — the RP93 is NOT included and I’m selling it separately (available only as a separate purchase). EQ2 light does not work as shown in the Youtube Video.
