Royal Crown

British Rock Amplifier

Got a question about this product? Ask us!

Based on arguably the "true" original British amplifier, the SonicTone Royal Crown brings an absolute classic tone to the SonicTone line up. The journey of this style of amplifier is an interesting one. It started as a clean, crisp amp, powering pop rock groups in the late 50's and early 60's. Then, as other new options arose in the British amplifier market, this amp evolved to keep up with the times. By the time the 1970's rolled around, this amp could not only hold its own against its British rivals, it had a dominate market share on the stage of some of the most famous bands of all time - contributing to those bands unique, stand-out sound. It truly captures the tone and spirit of that sound in a small, but powerful package.

Don't be fooled by its humble, classic origins - this amp is a titan of rock tone - delivering everything from chime-y cleans to rich harmonic overdrives.

Recommended Speaker Pairing: Celestion 25-watt Greenback(s) for accentuated overdrive, or a 15-watt Alnico Blue(s) for a more vintage, mellow sound.

SonicTone RC30. Does the AC-30 thing better than an AC-30

I had been wanting a Vox AC30 for quite some time and was finally ready to take the plunge. I tried several versions of the newer AC30's, but I wasn't overly impressed. I knew I loved the tone my hero's were getting on older records, perhaps I needed a vintage one? Then I heard about a local builder here, creating new versions of old classics. I called him and set up a demo at his shop. I went in wanting the RC30, but every amp I tried sounded so good, I actually had a difficult time deciding. In the end, I did get my RC30. The clean is that chimy, yet full sound you know and love, and the drive side has a lot more on tap than a typical AC30 does. This amp sounds great no matter what settings I use on it. I've let several people use it in my small home studio and always get the "woah, where did this thing come from?" Nick was great to work with and even helped me when I needed a custom cable to control the channel switching, as my midi switcher used a different protocol than what his designs do. The man knows his stuff, and you will not be disappointed with any of his amps.
