Hi-Fi + Volume Fix

The DL4 and MM4 are two of the most used pedals in the professional world yet they have a few issues. In stock form they suffer from a volume drop when they're engaged as well as some clarity and noise issues on certain settings. We fix the volume issue, noise issue and add more clarity, focus and response to the unit as well as installing super bright white LED’s.

Switch Replacement

We repair a LARGE number of Line 6 modelers with failed switches. This is due to the very poor quality and function of the stock switch. We replace these prone-to-fault switches with HEAVY duty fluid momentary replacements. You will notice a smoother push as well as more reliable switching action. Make your pedal road worthy and never worry about your DL4 again!

Expression Knob install

This mod is a must for the “tweaker”... You can have your expression function right on top of your pedal! No bulky expression pedal, just more options with less fuss. Save more sounds and have more tweak-ability in the live environment. This mod also enables some sweet noise and ambient tones that you didn't know the DL4 could do! Another added bonus is it's kind of like having six presets instead of three. With the knob turned off it is the stock preset, and then fully clockwise it is a second setting. This enables you to have three presets with two variations of each and all the in-betweens!

External Tap Tempo Jack install

This is a mod that may change your life. Honestly. We add a jack on the right side that allows you to remotely control your DL4’s tap function. This is an awesome addition for a couple of reasons. The first is that you can have your DL4 on the top of your board and have your tap control anywhere! The second is that you can sync your DL4 with ANY other tap devices using one single tap tempo switch like our “Mini Dual Tap Tempo” pedal. Imagine your Boss DD5 or other tap delay in sync with the DL4 but set at a different beat or mode!
