tube preamp

I love this preamp but it has been sitting on a shelf for over a year. It has not been required for the types of shows I do these days. In mint condition, 100% functional. Just time to thin the heard. US$500 shipped CDN$700 shipped

Mint condition with power supply and info card Quick catch and release on this one for me as I purchased another preamp at the same time which suits my needs better. Glad I got to try it, very good sounding with lots of flexibility, fits nicely on a small pedalboard. Payment via PayPal G&S...

This is an older version without the DI but has a high output and a similar noise floor to my DI pedal. It can give you that nice tube warmth, boost, overdrive or fuzz. Comes with 3 tubes to switch around with including a 12AY7, 12AU7, and 12AX7. Has footswitches for on/off and modern/vintage as...

I must be on drugs! This combo is awesome. But I kinda want another Barefaced cab AND I kinda want an all-tube amp. So if you have a Barefaced cab and/or an all-tube amp, those would be my only trade considerations at this point. This is an awesome combo that I gig with regularly. It is 375w at...

This little guy has a tube preamp and a class D power amp, and it sounds and looks amazing, while weighing only 12 pounds. In a fetching vanilla tolex. :) I bought this in great condition, and I've only played it at home, so it still looks and works like new. Comes with a gig bag. Price...

I am selling my Millennia TD-11 preamp. It is in nice condition with some signs of wear. These are absolutely killer preamps with option to run in dual-triode 12AT7 tube mode or a discrete FET solid state mode. With the push of a button, you can have a tube preamp or a FET solid state preamp...

This is an unusual, feature rich preamp, made by Dean Markley in the 1990s. Dean Markley had a number of pre's and amps in this two rack space format. Some were two channel, which they chose to call "DR" for dual row. The "DB" in it's name, contrary to some internet you-tuber, does NOT stand for...

Selling a Shaw Tube Injection preamp along with a nice case and a few additional tubes. I bought this here on TB several months back and it looks and sounds great. However, my playing has been severely curtailed due to work travel, etc...and this is just sitting around and needs to be used by...

Hi fellas!!! I'm selling this excellent condition Nobelium tube bass pre/DI in graphite gray!! This one has two JJ 12AX7 tubes, and a Lighting Boy transformer. Sounds really great, with the warm lows and defined tone you want from a tube-driven device, plus I fund the low-cut switch a great...

Hello, This is the non-DI version. One of the earlier models. I believe I'm the 2nd owner. 100% functional and sounds amazing. I liked it so much, I just bought an Arkham Beast of Both Worlds instead. Only thing of note is that when I took the velcro off the bottom, a small amount of paint came...

Hello, Awesome sounding pedal and even better sounding with the "updated" NOS RFT EF86. The original tube is also included as well as original box and all packaging. Please let me know if you have any questions.

A iconic tube preamp that needs no introduction! Full punchy clean tube tone with a front-facing direct out, biamping capabilities, and effects loop. This preamp was part of an incredible sounding lead sled that saw very little action other than a coffeehouse gig and several rehearsals in my...

Hand-wired bass preamp from the golden age of Aguilar amplification! These are rare for good reason. They have incredibly full, fat, punchy but articulate tube tone. I have a db680 that gets more attention so the db659 is off to a new home. This preamp has only been used for a few rehearsals...

Mesa Boogie Subway TT-800 for sale, bought new in early 2023 (February) and used/tried out at band practice a few times before deciding it didn’t beat my other amp. Would’ve kept it as a solid back-up amp but, I’ve already got a worthy backup and a new cab is on the horizon. $1050 shipped...

Two rare ones here in high demand. Rightfully so. These are holy grail preamps. First up, the Kern IP-777 In very good condition for its age. A few scrapes as you can see in the photos. All works just fine and of course, it sounds huge, fat, and tubey. Simply stellar! $1,100 shipped CONUS...
