Variable Amplified Thoughts

Man, I’m busy! But I like to be busy. Just busy enough where there’s always something to do, but never so busy that I can’t keep up with commitments. Fortunately, I’m cruising right along, and the only things getting neglected at the moment is the grass in the yard and catching up on DVR recordings of “The Dead Zone.”

Great news! First… I have been commissioned to build a custom 100 watt screamer for a new friend of mine, Robert Moore, aka Delicious. Robert is a very cool singer and guitarist fronting his own band (called “Delicious,” what else?) and I had the pleasure to fill in last week at their gig in Evansville IN. Robert, Billy, and Allen really liked my Granger H50 that I was playing, and Robert decided he wanted a Granger amp. After discussion, we’ve decided I’m going to build his very own custom signature amp (something I don’t even have yet, hmmmm), complete with his name on it (DELICIOUS CUSTOM 100), and some really cool features. It’s going to be a hyrid Mesa Boogie/Soldano footswitchable 2 channel amp (I’m breaking tradition, ha!), voiced to his preferences, and I promise… it WILL scream! Work starts as soon as the parts start arriving!

Next up: I have a JCM800 2204 build on the bench and it’s nearly done. While I have an original Marshall 100 watt 2210 made in 1987, I’ve always wanted a single channel 50 watt, so it’s nearly a reality. I’m going to house it in a custom, black & red, two-tone head cab as well. I’m expecting once people see and hear it I’ll start getting a few requests to build them.

Finally (for now) I’ve been commissioned to build a faithful replica of a 69 era SuperLead Plexi, and my client has already sourced all the parts, which will make my job much easier and I know he’ll get exactly what he wants. I should be starting on that next week. I’m very excited about it, and I’ll post photos/clips just ASAP.

Until my next posting, take care, have a great summer, and great tone to all.

From Rich:

This has been discussed multiple times in multiple forums. Usually, the discussion dies down quickly when someone with materials engineering experience provides some science. Bottom line is that cryogenic treatment will provide no benefit to the materials used in tubes (kinetics (changes) slow down exponentially as temperature decreases).

Cryogenic treatment makes sense for certain steels, when the desire is to induce more hardness (steels go through a martensitic transition at low temperatures).

Weigh each before deciding. I personally haven’t tried these treated tubes yet, so I won’t pass judgement.

Hey all. This is were I was supposed to include all the details and information about my latest build, the Granger H50. By now I’ve got 3 video clips up on YouTube, and a few photos in the gallery. Sorry for being a little late with it.

Anyway, I have a new channel on YouTube! I’ve posted the clips and a 4th is uploading. The issue is I need to find a converter to compress the video clips, since the output of my camera is avi, and the files end up very large - and even with a great DSL connection, take a long time to upload. So any help or ideas there are appreciated! I downloaded and installed Blaze Video, but it ended up wrecking playback of avi files, and I obviously don’t have time to sit all day and download different apps to try. As soon as that’s solved I hope to start posting a lot more clips, both demos of the amps, and maybe some of my observations about the actual building and testing phases.

All that being said, I am VERY VERY excited about this amp! I’m going to play it tonight at Citizen Jayne’s gig, and many more I hope.

The amp is based on the Hiwatt DR504 circuit. Most of the parts are from Weber. I’ve grown quite fond of them over the last couple of months. They have great customer service, always pack the shipments extremely well, and always try to accommodate my requests, such as custom faceplates. The best thing is, they have great prices, so it allows me to pass the savings onto my customers. I’m of the belief that a great sounding handwired tube amp shouldn’t cost $3 grand, which most guys (and gals) can’t afford or don’t want to pay. No offense to Hiwatt, Marshall, et al intended.

My thoughts on the amp - superb tone, extremely loud, very clear, bell-like at cleaner settings, very interactive controls. Really nice clean tone that is really responsive, great crunchy tone at higher settings w/ the master up and pre backed down. The bright channel is my favorite, but the normal channel does the best clean tone. Sound great with both a Tele and a Les Paul. With the pre control up and the master about half way the amp kills! Moderately high gain, plenty of sustain and feedback available.

So, check it out the clips on YouTube, and the photo gallery.
