DryBell Unit67

The DryBell Unit67 is an analog pedal that puts a compressor, a two-band EQ with a Rangemaster-style midrange control, and a clean boost in one compact box¹². DryBell, a Croatian manufacturer, describes it as a "Tone Shaper, Compressor, EQ, Booster, Rangemaster"³, and it was the company's first product outside its Uni-Vibe line⁴. The compressor is a low-noise FET stage inspired by the UREI 1176 studio compressor, with Attack, Release and Ratio fixed inside the pedal, and it works as parallel compression, so you blend compressed signal with your dry signal to keep pick dynamics⁵⁶⁴.

What it does to your sound

The pedal works as an all-in-one tone shaper. One tester described it as "a combination of a clean boost, compressor, EQ, rangemaster and whatnot"⁶. The compressor section is transparent, with a parallel blend circuit controlled by a single Sustain knob, so you can add sustain while retaining pick dynamics⁴. The EQ offers Low and High controls plus the Range control, which shapes the midrange⁶⁵. The boost stage reaches up to 22dB of gain², and the whole signal path runs on an op-amp based design with a high-headroom boost stage working at 23V internally¹⁵.

The controls

The big center knob is a vintage Davies Molding Daka-ware knob, chosen so the output level can be adjusted with a foot while playing¹. Around 10:00 on the Boost knob represents unity gain⁵. The input signal can also be reduced by up to 7dB at the minimum setting, fully counterclockwise⁴.

Power, bypass and connections

The Unit67 runs on a 9V supply drawing 100mA, mains powered only, with no battery operation²⁹. It uses a buffered bypass rather than true bypass². DryBell's development article explains why: in early true bypass prototypes, parasitic capacitance between the main circuit's input and output created oscillation problems with certain pedalboard switchers, such as the Boss ES-8, so the company instead designed an ultra-low noise, high-headroom buffer (14.0Vpp, 16.1dBu or 13.9dBV)¹. Pedal of the Day described the result as a buffered bypass with high headroom and an ultra-low noise buffer circuit designed for zero signal loss⁵.

Input impedance is 900kΩ at 1kHz and output impedance is 250Ω at 1kHz². DryBell offers a 14-day trial period with a full refund, and direct orders ship from the workshop in Croatia with a handmade leather keychain pick holder².

Where it came from

DryBell was previously known for Uni-Vibe recreations, and the Unit67 was its first non-vibe product⁴. The compressor is voiced after the UREI 1176 rack compressor²⁶, and the Range control draws on the Dallas Rangemaster, the vintage treble booster⁴. DryBell's designer Zvonch crafted the low-noise compressor circuit and perfected its feedback network¹. Development was not entirely smooth: early PCB circuit routing caused crackling on the boost potentiometer, which was later fixed⁶, and an unreleased V-1 of the Unit67 existed before the released version⁶.

The release date is reported differently by different sources: DryBell's own press reviews page dates the release to June 19, 2024⁷, while Delicious Audio reported the Unit67's release on August 16, 2021⁴.

What reviewers said

The review rated the Unit67 9 out of 10, calling it "a clever tone-improver that's easy to use yet brilliantly versatile"⁹. It found that "it does exactly what it's supposed to do with supreme assurance," while noting it is "undeniably pricey"⁹. On the compressor at maximum sustain, the reviewer found strummed chords had their transients "ruthlessly crushed, replaced by seemingly eternal sustain," while single notes were "sweetly thickened with a hint of thump to the attack," and dialing the blend down to halfway recovered treble and made the compression feel more natural⁹. The reviewer called the midrange control "the real star," going from a gently glassy scoop to full-on honky rage⁹, and described the boost as semi-clean, starting as an uncoloured level-lifter but rolling off a little top and bottom beyond one o'clock⁹.

Pedal of the Day called it a 4-in-1 pedal in a surprisingly small package, and the site's reviewer said it went straight onto their demo pedalboard, making everything around it sound better overall⁵. Delicious Audio noted the pedal was getting a lot of positive feedback, pointing to Bjørn Riis's review on Gilmourish⁴. Pete Thorn reviewed the Unit67 on YouTube⁶.

Who uses it

Rex Brown of Pantera uses the Unit67 on every pedalboard he plays, with both bass and guitars². Steve Stevens, guitarist for Billy Idol, is listed among DryBell's artists⁸, as is Brad Whitford of Aerosmith¹¹.

Versions and pricing

The Unit67 comes in a Red Edition and a silver color version¹¹. Both are listed at USD 289.00⁸¹, and DryBell has also offered B-stock silver units at USD 245.65¹. Guitar Pedal X listed the pedal at €319 / $289 in October 2026¹².
