Divided by 13 FTR 37 Head – New Boutique Tube Amplifier

No Sales Tax For Customers Outside Of California.

Mahar's Vintage Guitars is an authorized dealer of Divided By 13 and Two Rock amplifiers.  We also have the matching cabinet for this head.

We were blown away by the FTR 37 when a used one wandered through here last year.  It lasted in the show for about two days and departed.  I was glad to hear that Two Rock had purchased the company.  I saw the amps in production when I visited their facility and was impressed by the hands-on attention each build gets.  It was an easy decision to jump on board, both with Two Rock and Divided by.

Developed with the most iconic American and UK amplifiers from the 60’s and 70’s as the inspiration, the FTR 37 features two uniquely voiced channels and all tube spring reverb to offer a broad palette of bold clean tones, gritty overdrive and smooth distortion.  

The amp is laid out very simply, making it a quick study despite being incredibly flexible.  

Channel 1 delivers harmonically rich “UK” style overdrive, compression and sustain while Channel 2 offers the refined cleans, bounce and edge of breakup associated with the best “American” designs. The channels can be used independently or combined when used with an external ABY switch or Switchazel for the perfect blend of each circuit’s unique character and response. 

Unlike traditional amp-based reverb designs, the FTR 37 can control the signal that is sent to the onboard spring tank as well as the processed signal being returned. This allows the character of the reverb to be determined independently, prior to it being mixed with the dry guitar signal. This allows for a wide range of reverb textures, from subtle to full surf drip if desired. 

Equipped with a quad of 6V6 power tubes, the FTR 37 offers 37 watts of output to provide ample punch and clarity when used on large stages and outdoor performances where higher volume is required. Engaging the half-power switch reduces the output to 18 watts, allowing the power tubes to be pushed into saturation and natural compression at more manageable levels when used in smaller venues and recording sessions.  

All tube spring reverb with send and return adjustment, half power option, high and low sensitivity inputs per channel and unique dual voice capability give the FTR 37 the ideal combination of traditional tone with modern functionality to cover a wide range of genres and playing environments. 

TONE: A rotary switch offers six distinct capacitor variations that shape the lower frequencies of Channel 1. The full counterclockwise position provides less low frequencies. Turning the dial clockwise increases low frequencies. 

VOLUME/PULL BOOST (Channel 2): This knob controls the level of channel 2. Turning it clockwise increases the volume and adds overdrive at higher settings. When both channel 1 and 2 are in use simultaneously, this knob sets the level that is combined with channel 1. Pulling the knob outward engages an additional mid/gain boost circuit.

PULL BOOST –This function is activated by pulling the VOLUME 2 knob outward, increasing the mid-range frequencies and volume, causing preamp overdrive to occur sooner as the VOLUME knob is turned clockwise. 

FULL/HALF – This switch controls the amplifier’s output capability. In the “up/FULL” position, the power section outputs up to 37 watts. When switched to “down/HALF”, the output is limited to 18 watts, allowing the amplifier to achieve output tube distortion at lower listening levels. *see “Speaker Output Jacks” section for proper load selection when using the “down/HALF” setting
