An excellent tool for learning and giging

By Stevie V

from Olympia, WA

What a great tool for both practice and performing! I configure the PX4B using headphones and practice, playing along with music plugged into the AUX input. The PX4B clips onto my shoulder strap. With headphones and a portable MP3 player, I am free to wander about the house while I practice. I learned a 30 song set using the PX4B and my wife never complained. She heard the songs for the 1st time at the performance. On stage the Output is patched into my power amp (using the PX4B preamp) so the audience hears the same sound I have been hearing while I practice. I may get a rack mounted effects processor for stage performance, but I have not seen anything that can beat the PX4B for practice and gigging.


Sure does beat the BASS POD

I'm ready to throw my BASS POD in the trash, the Bass Pandora packs a lot in a small package. A great headphone amplifier too !


Amish Punk Bassist

Very high quality effects, and the price is nice, too. Works well with an Electro-Harmonix Bassballs pedal. You can record stuff, and the options for the user presets are awesome. Way to go Toneworks!!


PX4B Rocks

By Axman-EsOaG

from Naples, Italy

I don't know who rated this so low previously, but they are wrong. This little unit is an excellent way to get great bass sounds and practice right out of the box. It beats the Bass Rockman by far. I was amazed at the quality and variety of sounds. You can't go wrong with this.


Pretty neato

This thing is pretty awesome. I really like the drum machine and how you can plug in a stereo and it cancels the bass in the song you are listening to. I think it has great features: millions of different amp, cab, and effects combinations. The ToneWorks PX4B Bass Pandora is awesome. Simply put, I do not go to a gig without it.


Great PRACTICE tool.

Easy to use. Great for practicing quietly. Get an AC adapter. Batteries become costly when used a lot. Tried to use as a preamp in live situation. Forget it. Great PRACTICE tool.
