Bartolini is the best
By Michael TamTam
I wanted to upgrade my SR505 (2016), not because I didn't like that sound of the stock electronics, which I did like. I just really love the feel of that instrument so I wanted to make it the best it can be and perfect for recording. There's no noise or hum with this preamp, studio quality. BTW, I am using the Bartolini MK5CBC pickups.
Also, I always disliked the sound of flat EQ on my onboard preamp. This preamp already sounds great without having to boost or cut any EQ and I like to play slap and finger style.

Bartolini 5.4 AP preamp.
By william Voight
I had previously replaced the Bartolini mk1 pickups in my Cort Artisan A6 bass with the MK 6 Bartolini's. Retrofitting the Bartolini 5.4AP preamp to this bass was the icing on the cake.
The bass sounds terrific and the control setup is very flexible and having the option of shifting the mid range roll of points is a very useful addition.
