Took my LM741 clean boost concept further, once I had some knowledge of how to solder a board with the Op-Amps. The next step evolved around the ‘Center Stage’ Spring Reverb Design but adapted for LM741s. I built the device into the shell of an old Gallien Kreuger Backline 250 head, so now it looks like a giant stomp box. I think it sounds pretty cool, here are 4 demos, all recorded through an Epiphone Valve Junior on a very low volume. You can hear how the clean boost really brings some life to it. I don’t have time to do a full schematic , but the block diagram show give a good idea of how it works.

I’ve been playing around with LM741 Op-Amps, which are really cool little analogue solid state amps on a chip. My goal is to use them to build a box that can do spring reverb and also a clean boost….now clean boost you may say, what’s the point of that ? And of course there’s not much point until you put it in front of a small tube amp, when it allows you to push the pre-amp tubes into distortion at a low overall volume. And tubes don’t mind that kind of treatment at all…you can push much higher signals into a tube amp than you would really want to with solid state.
Anyway, here is a schematic of the prototype clean boost and a couple of demo tracks recorded plugged into just an Epiphone Valve Junior turned to just 02. This sounds great in front of my Sound Projects/Lectrolab R200 combo, my Valve Junior and my home-made Supro Thunderbolt analogue…really great, love it.
Braved it through Nemo’s snow to the Colonial Theater in Phoenixville, there to see John Mayall and his band. Any hairy moments on the road were well worth it as John and the band put on an outstanding show of classic blues and rock.
Despite being 79 years old, Mayall is still playing some solid keys and nice rhythm guitar and delivering great vocals and brilliant harmonica. Rocky Athos on guitar , Greg Rzab on bass and Jay Davenport on Drum seemed to be having a great time and all had their spotlight moments. Just a really great unit with all the chops and a deep feel for the music.
The set was varied and included a bunch of old classics, including Room To Move, Nature’s Disappearing and Hideaway as encore. The Colonial is a cool intimate environment with an appreciative blues crowd and the band seemed to relish it. Awesome show, I hope John Mayall can keep it going at this level for many years to come.
So back in my native UK, gas pumps typically dispense fuel at around 60 liters per minute. Here in the US the maximum rate is limited by law to 37.8 liters per minute.
So next time you are freezing your socks off filling the car you can blame congress for one more thing. Thanks guys.
Ugh – tax time looms and I just spent 15 minutes grappling with H&R Blocks on-line purchasing system….so why is it that web sites these days don’t bother to put little boxes and labels on fields ?
So you have to scrabble about looking for invisible fields without even knowing what information they want. And what dimwit still thinks it is a good idea to make you enter your email address twice ! Seriously ? We have been using this stuff for quite a while now.
C’mon web site designers and H&R Block in particular, get over the fashion statement and think about the customer !
Sad to see one of my Guitar Herores move on, even at the age of 87. Mickey Baker, whose ‘Guitar Method’ has been my friend for many years. Here is a link to his big hit back in 1957 – really cool guitar solo.
I ran the ATlantic City Half Marathon at the weekend…nuff said about that, but I was very pleased to catch a good deal of Robert Ross’s one man blues set at the Atlantic Casino Club, including a fantastic Ghost Riders in the Sky and soulful Sitting on Top of the World. Very elegant blues player and a fine entertainer…thanks !
Caught the Pork Roll Projects set at the Paoli Blues Fest on Saturday.
Fine set with nice playing from the whole band, really super solid bass and great harp were standouts. Lot of variety in the set with some funky , some straight ahead and some nice leads from Pork Roll himself. Great to see local bands pulling in a good audience and everyone having a good time.
Upgraded my system with a new M-Audio 192 Sound Card – I love this card ! It installed easily, it has regular 1/4 inch mono jack inputs and outputs, it has a nice software control panel to tune the performance and above all is primarily a music makers tool. The latency with Adobe Audition is miniscule right out of the box and the recording performance is exceptionally clear. Guitar recording sounds great but bass recording is really exceptional If anyone is wondering about the benefit of shelling out for a better sound card I would say consider M-Audio 192. I’m thrilled !
Very sorry to see the passing of Jon Lord. I’ve been a Purple fan since ’69 and his incredible organ sound was always such an essential part of their music. An absolute pioneer and creative master.
