JOYO Bass Preamp & DI Guitar Pedal

SpecPicks Verdict

SpecPicks scored JOYO Bass Preamp & DI Guitar Pedal using a rating × review-volume × price-fit model applied to published specs and reviews across the retro graphics cards category. JOYO's retro graphics cards lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for retro graphics cards of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.

Key Features

• BLEND CONTROL & DRIVE — CLASSIC 90'S BASS TONE WITH MODERN FLEXIBILITY: The TIDAL WAVE delivers the iconic punchy, articulate bass tone of the 90's with a dedicated Blend control that mixes your clean signal with the preamp's harmonically rich drive. Turn Blend counter-clockwise for pristine, transparent tone shaping using the 3-band EQ alone—perfect for pop, funk, and clean passages. Turn Blend clockwise to introduce the Drive circuit, adding everything from subtle warmth to aggressive, grinding overdrive ideal for rock and metal. Players describe the tone as punchy and praise the Blend for providing tight low end with just the right amount of grit.
• 3-BAND EQ WITH MID SHIFT & BASS SHIFT — PRECISE FREQUENCY CONTROL: Unlike standard 3-band EQs, the TIDAL WAVE features two toggle switches for surgical frequency control. The MID SHIFT switch toggles between 500Hz and 1kHz—cut at 500Hz to scoop the mids, or boost at 1kHz for a growly, cutting presence that slices through dense mixes. The BASS SHIFT switch toggles between 40Hz and 80Hz—select 40Hz for deep, sub-bass rumble, or 80Hz for tight, punchy low-end that sits perfectly in a band context. Combined with the Treble, Middle, and Bass knobs, you get studio-grade tonal flexibility.
• PROFESSIONAL DI & CONNECTIVITY — XLR OUT, CAB SIM & GROUND LIFT: The balanced XLR DI output connects directly to PA systems, audio interfaces, or front-of-house mixers—no external DI box required. Built-in cabinet simulation adds authentic bass speaker cabinet response to your XLR signal. A dedicated Ground Lift switch eliminates ground loop hum, while the Pad switch accommodates high-output active pickups. Note: Cab Sim is active on the XLR DI output only. The 6.35mm output passes your signal without cabinet simulation. For the quietest performance, use a regulated, isolated 9V power supply (not included).
• ROAD-READY R SERIES DESIGN WITH AMBIENT LED LIGHTING: Encased in a rugged all-metal aluminum alloy, the TIDAL WAVE features the iconic R Series ambient LED lighting with 3 modes (Sync, Always On, or Off) via a recessed switch on the underside—giving your pedalboard a sleek, professional glow. The smooth, responsive knobs and sturdy footswitch are built to withstand heavy stomping night after night. Note: The control knobs do not have numerical markings; we recommend noting your preferred settings during rehearsal for consistent live performance.
• JOYO QUALITY & AFTER-SALES CONFIDENCE: Backed by JOYO's decade-plus reputation for crafting innovative, budget-friendly gear. The TIDAL WAVE is part of the R Series, built with upgraded precision components. Important: Powered by 9V DC adapter only (center negative, not included). Rated current: <100mA. Battery operation is not supported. For the quietest performance—especially with high-gain drive circuits—use a regulated, isolated 9V power supply and avoid daisy-chaining with other pedals.
