OK - so where do I start? My name is Jeff Diamant. I am the owner of Diamond Amplification. To dispell the conjecture, we have no affiliation with Krank or any other amp companies currently or formerly on the market. I and my engineer have had this design working for a while, but until now, we did not decide to put it into production and offer it to the market.
I believe you will find that the amp bears no resemblence to Krank's heads, other than the use of the perforrated metal grille. Metal grilles are becoming more common (see Krank, Soldano and a few others). Some are using more stylized versions, but we wanted simple. They are made of stainless steel and all components (even the knobs) are high grade steel for feel and reliability.
As far as the head goes, it will speak for itself. As I mentioned to one poster, and as is noted on this board, amps are personal preference. While I like it better than what's on the market, there are certainly tonal qualities I liked in several products that influenced the tone. But you'll find it both similar and different from your favorite amps.
Unlike the suggestion, the tone is not an ultra-high gain with lots of sizzle and no separation. That is specifically a tone description we are staying away from. While there's plenty of gain (more than most if not all), the tone is beefy and full but designed to stay tight and focused in all frequencies. Players like Rusty were influential in that decision as lack of clarity in other products was one of his (and many guitar player's) complaints. Lack of separation is simply not a complaint you'll have in this head. (for those that don't know, Rusty's solo release was material and recordings that have been floating around for 10 years now - wait until you hear his new stuff from his band Outworld - both tonally and musically)
Sizzle either. That is a common complaint of a lot of guitar players. Keri Kelly had the same complaint of most "boutique" heads, until he played mine. That was one of his big compliments about the amp.
Regarding the grilles, I was conscious of the fact that other companies use them and similar ones at that. I made the decision to use that style based on the fact that (1) it's simple and effective; (2) it's more durable than grille cloth; and (3) it's more optimal for airflow.
About any alleged comments about other amps from me, I don't believe in bashing other amps. But I will, from time to time, draw comparisons on certain issues. The benefit is to give the listener a basis for comparison. It's one thing to hear me describe it, it's another to be able to relate it to something you've heard as a base line.
The price isn't based on the features. It's based on the tone, functionality and most of all, the quality of construction. I believe you'll find that my MSRP is a little under the most comparable products (SLO, Custom Audio's OD-100, VHT's Ultra Lead, Bogner Uber and Ecstacy, etc.). My price is above Boogie's, but my dealers will be permitted to discount. This is designed as a top of the line product, hence, the price. I'm well under a lot of the boutique heads charging over 3K for their products. Because we're building more of them, we can get the prices down for that level of product. There are certainly less expensive amps on the market. None that we're building, however. The future will hold a lower cost alternative (e.g. Soldano Decatone) but not substantially lower. I doubt we'll ever build a head much under an MSRP of of 1500-1900. It's too hard to retain the quality we want with cost that low.
