I fitted this as an upgrade (along with a set of EMG PJX pickups) to my Epiphone EBM-4 bass. The original setup utilised passive pickups with active electronics. The pre-amp board went on the original, so I decided to overhaul.
Instant new bass, I?m really happy with the results. The sound quality is far superior compared to the original setup. The bass and treble controls provide a nice level of boost/cut and the internal dip switches allow for additional tonal options.
I opted for an 18v power configuration, this required a little soldering. Well worth opting for the higher voltage supply as it ensures a really strong signal. You will need a second battery clip for this, only one is provided with the kit.
My output jack was a long barrel style one and I also had to solder its connections.
Pros:
Easy to install due to the quick connect system
Very clear instructions
All materials required were provided, including some shrink tubing if you have to solder like I did.
Cons:
These have long pot stems which didn?t fit 100% as planned however was overcome with some washers, so no big issue.
Verdict:
I?m very pleased with my purchase. It arrived on time and allowed for a hassle-free installation. A quality product, would highly recommend this.
