I’m a massive fan of the OBP-2 and OBP-3 preamps, they sound excellent and are very flexible. Highly recommend the pre-wired kits which are such a huge time saver!

Quality parts and easy wiring diagram. They were quick to respond and resolve a troubleshooting issue. Now I'm thumping with great tones. Thx FBT!

A lot smaller and less cumbersome than other preamps, but offers a nice control of tone.

I’m 💯 satisfied with 1st pre amp Aguilar OBP 2 that I purchased. This is follow up review cause I called Max last year about why my new OBP2 don’t have same thump as the 1st one I purchased . He told me the pre amp will not sound same in different bass . Now I gotta figure out what to do cause I ain’t buying another pre amp after getting 3 already I won’t waste another dollar .. plus having luthier to pay 💰 im out

I sought a preamp replacement for my Warwick Rockbass Streamer Standard, and the Aguilar OBP-3 proved to be an excellent choice. While I genuinely liked the guitar, it suffered from excessive noise at certain settings and had a lower output level than desired.

The OBP-3 preamp effectively addressed these issues and brought additional features to the table, such as active/passive switching and mid control. Although I already appreciated the original sound of the guitar, the OBP-3 enhanced the overall tonal quality.

The prewiring was well-executed, and the provided wiring diagram was clear and easy to follow. Replacing the preamp was a relatively hassle-free process.

One minor concern, potentially specific to my particular guitar, was that the MID pot with push/pull was too tall to fit in the desired location. Thankfully, the cavity had greater depth in another corner, allowing me to accommodate the pot without major complications.
