Designed to enhance passive basses or refine any amp’s tone, it offers versatile, high-headroom sound shaping with noise reduction features like a ground lift switch. Perfect for professional bassists seeking pristine tone and flexible connectivity in a space-saving design. ## Description The MXR Bass Preamp combines a pristine bass preamp with a studio-quality Direct Out in a Phase 90-sized box, providing clear tone without hogging precious pedalboard space. Use it to add a new voice to an old passive bass, sweeten up any amp, or put some special sauce on a particular song. Dial it in just the way you want it and send it straight to the house—pre or post-EQ—with the built-in Direct Out. The Bass Preamp features separate INPUT and OUTPUT level controls and a 3-band EQ section with sweepable midrange—from 250hz to 1khz—for extensive tonal flexibility. It’s all delivered super clean with high headroom thanks to our own Constant Headroom Technology, and you can use the PRE/POST EQ switch to set whether or not your Direct Out signal is affected by the Bass Preamp’s EQ section. And of course, the Bass Preamp features a GROUND LIFT switch in case you encounter ground loop hum. The Bass Preamp is factory preset to operate in ¼” out buffered bypass and Direct Out active. For players who only want to use the ¼” out, there are two internal switches that disable the Direct Out and ¼” out buffered bypass for true ¼” out bypass mode. ## Features - Separate INPUT & OUTPUT level controls - 3-band EQ section with sweep able midrange - Studio-quality Direct Out ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00I3TOXVM | | Amplifier Type | Solid State | | Best Sellers Rank | #68,061 in Musical Instruments ( See Top 100 in Musical Instruments ) #5 in Bass Guitar Amplifier Preamps | | Brand Name | MXR | | Colour | Green | | Compatible Devices | Double Bass | | Connector Type | XLR or 6.35mm Jack | | Customer Reviews | 4.7 4.7 out of 5 stars (190) | | Enclosure Material | Metal or Durable Plastic | | Global Trade Identification Number | 00710137072770 | | Item Type Name | Preamps | | Item Weight Unit of Measure | 227 g | | Manufacturer Part Number | M81 | | Model Name | 11081000001 | | Model Number | M81 | | Number of Items | 1 | | Output Channel Quantity | 2 | | Output Wattage | 15 Watts | | Power Source | Corded Electric | | Sound Profile | Versatile, adjustable EQ for shaping tone | | UPC | 710137072770 | ## Product Details - **Brand:** MXR - **Colour:** Green - **Compatible Devices:** Double Bass - **Material:** Metal or Durable Plastic - **Output Wattage:** 15 Watts ## Images ![MXR M81 Bass Preamp - Image 1](https://m.media-amazon.com/images/I/41xMhnUbRCS.jpg) ![MXR M81 Bass Preamp - Image 2](https://m.media-amazon.com/images/I/31qrkBv0icL.jpg) ![MXR M81 Bass Preamp - Image 3](https://m.media-amazon.com/images/I/31nptHDdbcL.jpg) ![MXR M81 Bass Preamp - Image 4](https://m.media-amazon.com/images/I/31zYx27srvL.jpg) ![MXR M81 Bass Preamp - Image 5](https://m.media-amazon.com/images/I/31Nqfipu+SL.jpg) ## Frequently Bought Together - Jim Dunlop Power Amplifier (11081000001) - D'Addario Accessories PW-CT-9V DC Power Adapter – Pedalboard Power Supply - Minimize Need to Change Batteries on Pedalboard and Other Devices Requiring 9V – Guitar Pedal Power Supply - MXR Patch Cable 6 in|15 cm - 3 Pack (3PDCP06) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.dk/products/221182939-mxr-m81-bass-preamp](https://www.desertcart.dk/products/221182939-mxr-m81-bass-preamp) --- *Product available on Desertcart Denmark* *Store origin: DK* *Last updated: 2026-09-24*
