Also a large range of adjustment compared to stock. - This is the exact sound that I was looking for and most reviewers would agree. If you are seeking a transparent preamp, you might want to look elsewhere but this product is a legend for the sound anyway. The included pots worked well and I purchased 2 additional 500k ohm pots to complete the total re-wire. Install is more advanced as the wires are quite small to solder onto the pots. I did notice there were harness available for a quicker install, but I was able to install without any issue. It is installed in a MTD Kingston Heir 4-string with the stock neck jazz pickup and bridge MM humbucker. I currently run this in a 9v configuration, but it can be setup for 18v if extra volume is desired. Review: Great Bass Response - I have recently had 2 Music Man bass preamps die on me. I replaced my Stingray 5 preamp with a new stock Music Man pre. However, I decided to use the Aguilar OBP -3TK/PP in my Stingray 4 string. I went with it over some of the other available preamps for a couple or reasons. 1) It is easy to find. Many of the other available bass preamps aren't stocked by stores or internet shopping cart available. They have to ordered thru a dealer who then orders from the manufacturers. I've not had good luck with that. Can take a long time to get it done. And buying a replacement from Music Man can have a bit of a delay time wise on it. Two weeks probably minimum getting it to happen. I didn't want to wait this long. Got this Aguilar in a couple days. 2) Friends told me this preamp was super reliable and I believe that. I've have nothing but praise for all the Aguilar gear I've owned. 3) The bass response on this preamp is thicker and meatier to my ears than competing preamps sounded. So far, that sounds right to me. It makes my MM Stingray 4 sound very phat in the mix but I still have tons of highs and this model gives me mids too. The character of the bass sounds similar but I think the bass response seems bigger. So I think it an excellent choice and I would buy it again if I needed a bass pre for another bass. ## Features - Includes stacked Treble/Bass pot and separate Mid pot.

If this is something you want to fully eliminate, you might want to look into getting a noise gate. The ISP Decimator is one that is highly rated, but there are other options out there. IMO, unless you are in the studio recording I wouldn't worry about the hiss too much. Good luck! **Q: Does this come with the knobs for the pots?** A: No it doesn't. I used the knobs from my bass. I purchased a stack knob for the bass/treble pot. **Q: Is this ideal for the mim Jazz V?** A: IMHO..I believe that the Aguilar OBP-3SK/PP will work fine for the mim Jazz V. **Q: Im experiencing a terrible sound clipping issue when preamp onboard is turned up. Is this common?** A: No. I think this is a malfunction or wrong wiring. Check all soldered spots and connections. If all done right contact your seller. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent replacement of original preamp.

The mid frequency select switch is an awesome feature with boost and cut at 500hz and 800 hz, its all that you need in the mid department, also the highs are crystal clear but has a lil bit of hiss when boosted fully. ## Frequently Bought Together - Aguilar OBP-3SK/PP 3-Band Onboard Bass Preamp - SAPHUE Guitar Dual Concentric Stacked Control Knobs Sets Metal with Wrench Replacement for Electric Guitar Bass 2 Sets --- ## 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.co.uk/products/8239645-aguilar-obp-3](https://www.desertcart.co.uk/products/8239645-aguilar-obp-3) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-20*
