Overview: Custom Tones is very excited to announce the release of the ETHOS 60’s Harmonic Bias Trem, (60’s HBT). The 60’s HBT design is based on Fender’s® 1960’s Brown Panel five triode stage Harmonic Tremolo Amplifier series 6G5-A, 6G14, 6G4-A, and 6G8, . The 60’s HBT creates Harmonic and Amplitude modulation by using Bias Shifting of Simulated Analog 12AX7 triode stages recreating that 60’s rich pulsating tone. The 60’s HBT is incredibly practical for the working musician where on-the-fly foot switching is available for FAST / SLOW Speed and HARMONIC / AMPLITUDE Mode modulation selection. Additionally, the 60’s HBT provides a volume trim (VTRIM) and EQ control (TONE) that allows the artist to balance the Tremolo signal against the Bypass signal. Specifications: I/O • Input Power: 9VDC (regulated), 100mA, Center Negative, 2.1mm x 5.5mm [Note: voltages greater than 9VDC can damage the unit] • Input: Instrument Input, ¼” jack, Zin = 1 Megohm (Active mode) • Output: Effect Output, ¼” jack, Zout = 10Kohm (Active mode) FOOT SWITCHES • ACTIVE: Selects Between Effect vs True Bypass • SPEED: Selects Between Slow and Fast Modulation • MODE: Selects Between Amplitude vs Harmonic Modulation Mode CONTROLS • SLOW SPEED: Controls Slow Tremolo Speed • FAST SPEED: Controls Fast Tremolo Speed • INTENSITY: Controls Depth of Tremolo • VTRIM: Controls Volume of Tremolo • TONE: Controls the Top End of the Tremolo DIMENSIONS • HxWxD 2.25"x 4.7" x 2.5" Specification subject to change without notice 

“TONE TIPS” SPEED CONTROL The speed controls cover 2 different speed ranges where the FAST SPEED range is roughly 2X the SLOW SPEED range. This offers an easy way of dialing in speed. For example when the slow and fast speed controls are set in the same position, e.g. 12:00, the fast speed will be 2X the slow speed. VOLUME TUNING Many times turning on a typical tremolo unit will change the guitar’s apparent volume . This is due to the effect of the peaks and valley’s of the modulation on the base signal when the INTENSITY is turned up. To address this the 60's HBT has a VOLUME TRIM, VTRIM for short, that offers a post modulation gain trim. Once you have set the INTENSITY of the 60'S HBT to your liking, you can adjust the VRTIM to the desired level comparing it to your bypass level. TONE TUNING Tremolo can sometimes effect the tone of your guitar especially when used in the HARMONIC mode where dynamic filtering is taking place. The TONE control provides a degree of post tremolo high frequency adjustment. This can also be very important when using overdrive or distortion pedals to balance out the tremolo’s tone with the added harmonic content of those devices. POWER-UP At power up internal bias voltages ramp up and stabilize after approximately 45 seconds. During this time switching the unit ON/OFF will generate subtle popping noise and the tremolo intensity will be low. Once the bias voltages fully charge the switching popping will cease and the tremolo intensity will be at its set level.
