From Carstens Amplification:

Carstens Amplification® Grace

Carstens Amplification® and Billy Corgan have combined creative talents to change the guitar amplifier game. Versatile, articulate high gain and supreme tone.

Brian Carstens has long been working with the Smashing Pumpkins as an amplifier technician. In late 2018, Billy Corgan and Brian began discussing an amp collaboration. Billy expressed, in over 30 years of creating music, “I have never played a high gain amp that I like.” Billy’s lofty request: for Brian to make him an amp with an unheard of amount of gain, high headroom and distinct tone. Brian got to work, and the Carstens Amplification® Grace amplifier was born. Billy was so blown away by the Grace that this custom project turned into this signature Billy Corgan amplifier — Billy’s first and only. To really understand why Billy Corgan calls the Grace “a game changer” and “a step forward,” take a listen.

This versatile, 100W, single channel amplifier offers a staggering amount of articulate high gain, yet is exceptionally responsive to changes in your guitar volume. As such, your Grace can go from clean, crunch to breathtaking overdrive with the turn of a volume, or gain control.

Each Grace is completely handwired using premium components, including specially designed, hand-wound Mercury Magnetics transformers. The result is a beautifully open and immense 3-dimensional high-gain overdrive with incredible note separation.

All are handmade by Brian Carstens.

Early Order Cancellation

All deposits are non refundable. Lots of our products are special orders and in many cases your order has to be built for you at the factory. This is what makes a lot of our products special. Once your order is started, it's being put together just for you. For this reason we ask that you don't cancel your order after you place it with us. If for some reason you absolutely have to cancel your order with us, we will assess you a 25% cancellation charge. This amount is equal to 25% of your total order amount. Ask us before you place your order to see if what you're purchasing is considered a special order.
