Well it's here, the Extreme Reverb review by Jake Lee - Mangrove Music.

Thanks for the kind words Jake, glad you like it 😁😁

I AM NOT SPONSORED BY BJ AMPLIFIERS OR RATAJCZYK (I just really like their amps!)The Ratajczyk Extreme Reverb is an all-tube amplifier made in QLD, Australia...

So last week we received an awesome email from a customer of ours Jake Lee - Mangrove Music. He stated he's owned his Cream Reverb since 2022 and it's been his favourite amp since the day he got it. He noticed there's not much content/reviews of our Amplifiers online. So he's used his Cream Reverb as the subject of his first Amp review. We were pretty impressed and want to share it with you all.

P.S there's a Extreme Reverb Review coming soon too 🤘 so give his page a follow and be one of the first to check it out.
