The SoloDallas CompanDrive 65 (CD65) is an overdrive pedal built around a companding circuit, the same compress-then-expand approach used on studio tape machines since the first Dolby noise reduction process appeared in 196512. Where a typical overdrive just clips the signal, the CompanDrive 65 squeezes it going in, generates harmonics in the middle, and restores its level coming out, aiming for the sound of a signal that has been through a professional tape chain1.
SoloDallas describes the result as "a secret recipe of warmth, harmonics and dynamics, producing that immortal studio tone of the golden era of recording"1. The pedal is 100% analog and made in the USA1. Premier Guitar covered the launch in May 2026, reporting a street price of $2492.
An overdrive built on a companding circuit
Companding, compressing a signal on the way into a gain stage and expanding it on the way out, is a studio technique rather than a traditional stompbox one. SoloDallas's product page says the CompanDrive 65 is "a faithful recreation of the legendary companding circuit found on virtually every studio tape recording since the introduction of the first Dolby" noise reduction process in 19651.
Guitar Pedal X framed the pedal as bringing "recording studio magic to your rig," noting that it combines compressor, expander, overdrive, and boost in one compact stompbox, and that it is "equally at home on a pedalboard or in the studio"3. Pedal of the Day noted the build uses a commercial grade PCB4.
The design keeps things simple on the surface. Guitar Pedal X counted the controls: "It has two controls: Compand Drive and Boost"3. Everything else the pedal does is fixed by the internal circuit order.
The four stages in the signal path
The signal path runs 1 to 4, and each stage has a defined job13:
| Stage | What SoloDallas says it does |
|---|---|
| 1. Vintage Console Gain Circuit (VCGC) | Uses the famed LM308 op-amp; produces "rich, hi-fi overdrive with abundant harmonics while subtly shaping frequencies to add fullness, presence, and clarity in the mix"1 |
| 2. 65 Compressor | "Delivers a smooth, blooming soft-knee attack that enhances note separation and adds musical harmonic clipping without choking dynamics"1 |
| 3. 65 Expander | "Restores overall signal amplitude, removing unwanted 'pump and squish' while further emphasizing the harmonics generated by the VCGC and compressor stages"1 |
| 4. Vintage OpAmp Boost | "A classic op-amp design that preserves delicate frequencies and maintains clarity as output level is increased"1 |
The LM308 op-amp in the first stage is the same chip family associated with classic RAT distortion circuits, which gives the overdrive stage a point of reference for players comparing it to other drives1. The compressor and expander pair is what separates the CD65 from a straight overdrive or boost pedal: the compressor shapes the attack and adds harmonic clipping, and the expander then undoes the level squeeze so the dynamics survive12.

Power: 12 to 15V, 200 mA
The CompanDrive 65 runs on 12 to 15 vDC, center negative, drawing 200 mA, and takes PSU power only, with the power supply sold separately1. Its 200 mA draw should be checked against whatever supply powers it.
That voltage range and current draw mean it needs a supply that can deliver 12 to 15 vDC at 200 mA, and the pedal is PSU power only, with the power supply sold separately1.
Where it goes in a chain
Guitar Pedal X describes the CompanDrive 65 as intended for front-of-chain use, sitting first in the signal chain where a compressor and boost normally go, before drives and time-based effects3. With its compressor, overdrive, and boost functions in one box, it can cover the front-of-chain slot on a pedalboard on its own.
What reviewers said
Guitar Pedal X's Stefan Karlsson reviewed it in April 2026 and came away positive about both the sound and the layout3:
"I really like the sound of this too - and like the simplicity of its makeup - just 2 simple controls - which combine a number of different circuits within the one confection"
At the time of that review the pedal was available for £205 and equivalent as a pre-order price3. Premier Guitar's launch coverage confirmed the four-stage analog design, the true bypass footswitch, and the $249 street price2.

Questions
Can the CompanDrive 65 run on 9V?
No. SoloDallas specifies 12 to 15 vDC, center negative, at 200 mA. A standard 9V pedal power supply does not meet the pedal's voltage requirement, so it needs a 12 to 15V supply capable of delivering 200 mA.
Does the SoloDallas CompanDrive 65 take a battery?
No. The pedal is PSU power only, and SoloDallas sells the power supply separately. There is no battery option, so it needs an external 12 to 15V center negative supply on the board.
Is the CompanDrive 65 true bypass?
Yes. SoloDallas fits a heavy duty true bypass footswitch, so when the effect is disengaged the signal passes through without the pedal's circuitry in the path. A blue LED lights when the effect is on.
Where should the CompanDrive 65 go in a pedal chain?
Guitar Pedal X describes it as intended for front-of-chain use, combining compressor, expander, overdrive, and boost in one unit. That puts it first in the chain, before drives and time-based effects, where a compressor and boost normally sit.
How much does the CompanDrive 65 cost in the US?
Premier Guitar reported a street price of $249 when the pedal launched in May 2026. On SoloDallas's own site the sale price is £189.00 GBP against a regular price of £212.00 GBP, with EU customers directed to a separate SoloDallas EU webshop.
