Get the Sound You Want from Your Onstage Instrument!

Radial's Tonebone PZ-Pre 2-channel instrument preamp is a feature-loaded onstage essential! Featuring a 3-band EQ, variable notch filter, and filter, the Radial Tonebone PZ-Pre helps you kill feedback quickly and easily, and separate piezo boosters on each channel give your pickup-equipped acoustic instrument some real punch. Also included are separate pre- and post-EQ DI outs for monitoring and FOH connections, as well as a tuner out with footswitch mute. A power booster for soloing is also onboard the Radial Tonebone PZ-Pre.

Radial Tonebone PZ-Pre 2-channel Instrument Preamp at a Glance:
  • EQ and filters fit for the stage
  • Great connection options
  • Footswitchable functionality
EQ and filters fit for the stage

Knowing you're in control of your sound onstage helps you to perform your best. If you've ever had to plug your pickup-equipped acoustic guitar into a DI box onstage and leave the sound you hear in your monitors to the mercy of the FOH engineer, you know how powerless you can feel about controlling your instrument's tone and volume. Radial comes to the rescue with the Tonebone PZ-Pre, giving you a 3-band EQ with a semi-parametric mid control to shape your tone before it even leaves the stage. This versatile pedal's notch filter helps you fight feedback effectively, while a highpass filter removes rumble and other low-frequency noise that might effect your sound. If your pickup's output level needs a pick-me-up, the Tonebone PZ-Pre also includes a piezo booster on each of its two channels, so your volume and tone will always be robust and clear.

Great connection options

Connections are plentiful on the Radial Tonebone PZ-Pre. You get a pre-EQ balanced DI out for the front-of-house mix, a post EQ and effects loop balanced DI out for in-ear monitoring or on-stage wedges, a separate tuner out, and a personal guitar amp out. The Tonebone PZ-Pre has everything you need to stay connected onstage!

Footswitchable functionality

Radail not only packed a ton of functionality into the Tonebone PZ-Pre, they made sure you can easily access what you need when you need it. Want to tune up quickly? Just hit the mute button and you and your tuner are the only ones who'll know. Toggle between the PZ-Pre's two channels for tonal flexibility. Solo time? Hit the boost switch and you'll get increased volume that's sure to cut through the mix.

Do Your Tone A Favor!

I had been coveting this little box for far longer than I'd like to admit. Sure, I received the occasional compliment on the guitar tones I was getting during solo and duo shows.... but, It just seemed like I was never truly buying in to the acoustic tone I heard coming out of my PA. So, finally, I pulled the trigger and got the PZ Pre. The first time I plugged in and started finger picking, I was convinced a little man had crawled inside of my EONs with my Martin and was playing away. Really, the sound difference was THAT dramatic. I've put this thing through it's paces, utilizing the boost and loop functions, I've scoped out the frequency cuts available with the filter, dug in to the very musical "a little goes a long way" EQ. It's undoubtedly the biggest bang for the buck improvement in my live sound since adding a subwoofer. I haven't used it in a full band setting, but I could see the filter being incredibly useful in giving the bass player a nice mud free zone in which to do his or her thing. I am putting a cheapie backup guitar with an even cheaper soundhole pickup into the 2nd input as well. Initially, I was a bit concerned with the fact that the signal was so weak in comparison to the active pickups in my Martin. But, problem solved. The PZ Pre has a boost option, which is cleverly configured so that when you activate the boost, you can also activate the loop, or not. Thus, when I instantly switch to my 2nd guitar I have all of the gain that I need with one click. And, the tinny, tubby tone I was getting with the cheap guitar in open D tuning I was using suddenly became a head turning sound! Add to all of this the fact that it's made by Radial and is built so ruggedly that it may well outlast me? Do your tone a favor.....

A Great Product Live and Studio

I play a Taylor 514ce that I've had for over 12yrs .I used to plug into a Trace 30 acoustic amp .With some tweaking I could make it sound very good . I sold that amp and was temporarily using my JBL PA w the 15 inch speakers. It sounded passable but mostly brittle and not naturally pleasant. Once I connected the PZ-pre the" Magic " began to happen . I've been playing for 50 yrs and have never heard an amplified acoustic sound so beautiful and natural . On top of that you get so many options for live and studio applications that I just love to play through this pedal for any acoustic performance. Thanks Matt this was a great buy , a true joy to have such a musical tool .

Flexible, Accurate and well worth the investment

Of friend of mine suggested I try this piece, as he uses it as his main acoustic guitar preamp and his live sound is beautiful. So, I bought one on his recommendation. I ended up using this pedal for the next three gigs I had - 1st night, as an upright acoustic bass (piezo pickup) pre, 2nd night for an acoustic guitarist with two guitars (love the switching and fb notch) and the 3rd night on an electric/acoustic bass. What a joy! Wonderful sound from all sources and many compliments. Finally, used it again this past weekend on acoustic guitar for a national touring artist who has a rather complex rig (but was unhappy with her sound/tone). Well, the PZ Pre is now on her list of 'Must Buy' as it gave her a solid, full tone and cured several problems in the touring rig. Try one, buy one - you won't regret the addition to your rig or backline 'toy box'.

Wish I hadn't waited so long,,

I've got a bunch of wonderful sounding guitars, but this PZ-Pre makes great sounding guitars sound even better...a full, rich sound, It came with a simple, easy to understand owners manual and the unit itself is quite intuitive and "user friendly." If you follow their suggestions I don't think one could be disappointed. I really like its layout. It's switches and in/outs are arranged and separated in a way that makes them quick and easy to visually and manually access. It's steel housing seems tank-like in durability. I've only had it for a few weeks now, so long term reliability remains to be seen. I'm usually fairly slow in evaluating and giving either a negative or positive review on any product, however, I'm very pleased with this PZ-Pre and the functionality and sound it provides.

Just what I expected from Radial -- another excellent product!

Extremely versatile and easy to use. However - advertising isn't consistent in visual presentation (photographs in print ads, website and even on the box). All visual ads show a different unit (color scheme and placement of controls and control and toggle descriptions). The screws are now Phillips instead of the preferable Allen screws shown in ads.
