Chandler Tube Driver Rackmount - Awesome!!

This is a legendary 1988 Chandler Tube Driver (TDR-101), bought new and owned since then by myself. Very clean for pushing 40 years old! The least expensive one of these available online now is over $400 including tax and shipping, so this is a VERY good local deal for someone that has always wanted one of these ... They will only get more expensive. This is THE one to own. It has everything the fabled foot pedal version/model (Eric Johnson, Billy Gibbons, etc.) does and MORE!! These are also used by the great Johnny A, who has a rack full of them that he uses like different channels on his amp rack setup. And yes, it does have that touch sensitive type reaction to your playing, where it can get more aggressive and responsive when you dig in, or clean up when you lay back on your picking attack - just like all great tube based units. Im the original owner. I bought two of these around 1988-89. The other one is long gone. Ive used this one on and off mounted in a rack and its ALWAYS sounded fantastic and worked perfectly, as it does now. It adds depth and dimension, as well as boost, overdrive and warmth if you choose. The front panel has Boost and Bypass rocker switches, Drive, Contour, Bias, Master, Hi. Mid. Lo knobs and a rocker power switch. The back panel features Line and Instrument 1/4 jacks, Line and Instrument 1/4 Input jacks, and a 1/4jack each for a Boost and Bypass foot switch. Built-in power supply. The Contour knob can go from scooped mids EQ to mid-forward tone, with everything in between. The Bias knob works directly on the real AX7 tube in the unit and can add thickness, juice and overdrive - Very cool. Can be used in the studio (or live) as well to warm up synths/keyboards and other instruments/sources. I used it live a lot with a cabinet emulator and went direct - it worked incredibly well. It can also be used in front of any amplifier or in a rack setup, of course. Its very quick and easy to swap out tubes in minutes to try different tones and drive amounts. It takes 12AX7, 12AT7 and 12AU7 varieties all just as well, without anything required other than pulling one out and plugging another in. It currently has an almost new Bugera 12AX7 in it, but will also come with a used Sovtek 12AX7LPS that has a more aggressive sound. On the Chandler Tube Driver, the contour knob shapes the overall tonal balance by adjusting the midrange frequencies, allowing you to dial in a scooped mids sound if turned towards the scooped setting, or emphasize the mids if turned towards the flat setting, effectively influencing the character of your tone without drastically changing the overall gain level. Key points about the contour knob: Midrange focus: Its primary function is to control the prominence of midrange frequencies in your sound. Tone shaping: Turning the knob clockwise generally increases midrange presence, while turning it counterclockwise reduces midrange, creating a more scooped tone. Versatility: This feature lets you adapt the Chandler Tube Driver to various playing styles and genres by fine-tuning the midrange character. The bias knob on a Chandler Tube Driver controls the operating point of the internal tube, essentially affecting the overall character of the overdrive sound by adjusting how hard the tube is pushed, with a lower bias setting producing a more compressed, smooth tone and a higher bias giving a more aggressive, bitey sound. Key points about the bias knob: Tube operation: In a tube, bias refers to the idling current, and adjusting it can change how the tube reacts to signal. Tone impact: Turning the bias knob lower will generally result in less gain and a smoother, more compressed tone, while increasing the bias will add more gain and a sharper, more aggressive sound. Experimentation: Many guitarists use the bias knob to fine-tune their desired overdrive character depending on the playing style and music genre. I hate letting this one go, but Im not playing as much now and have gone to a pedalboard for ease of use in my current setup, so its time to move this on to someone who will enjoy it as much as I have for nearly 4 decades. Meet in Charlton at the CVS - S.E. Corner of Route 20 and 31. You wont find one working and in this condition at this price, period. Im not hard-up for cash, so if it doesnt sell for my price, Ill just hang onto it. $300 FIRM - Cash Only, Local Pickup Only, No Low Ballers or SCAMMERS Text or call will get the fastest reply Thank you ~
