Here are a few clips of both these amps (after mod) recorded with an iPhone so you get a better idea of what the amp sounds like in the room and not 2 inches from the speaker 😄

Big thanks to all of you for your kind words! 🙏🏻

Thanks for your input, Larry! If everything goes well I will have the first prototype up and running within a few weeks. Yes, I'm a big fan of the old Partridge irons and I have those in my personal amp (Laney PA 100) which I rebuilt over 10 years ago. The Hermansson transformers are made in...

The Hermansson 100W transformers have more iron than the 250W Marshall JCM800 model 2000 I recently rebuilt for Fredrik Thordendal 😅. My chassis are ordered in 2mm stainless steel. 💪🏻

Yes, my Malmberg cab is equipped with greenbacks. Three of them are from 1973 and one is pre rola from 1970. All 25W 75Hz.

Really enjoyed listening to your playing! 👏🏻 Try the tightness switch in down position and set the tightness control to max, gain about 5/10. Then you should get growling and thick distortion which is elastic (for soloing) but enough tight. /Henric

Guys! Thank you for all your kind words about my work! 🙏🏻 Here’s a video of the new channel with 3 gain stages:

I've rebuilt another Carlsbro amp! This was a Carlsbro CS60, a four-channel PA with spring reverb. It's rebuilt to a one channel metal amp with an effects loop. The controls are: three-way-mid-boost-switch, tightness, gain, bass, middle, treble, volume, punch...

It's a Carlsbro 100 watts 7 channel mixer amp which I've converted to a one channel metal amp. It's my five-stage metal circuit and I've kept the original master section and put it on a switch so it can be switched in and out. The amp has the following controls: gain...

Hi guys! It's been a while since I posted any clips on RT so it's about time I share one of my recent amp builds with you. This is what it looked like when I received it: Cleaning out the old circuits: And the result: The amp has two footswitchable...

All three channels modified, channel 1 is crispier and more open sounding and channel 2 and 3 are way more aggressive and tight. These amps have a layout problem from the factory which makes them noisy, I've changed the layout in my mod and the result is a quieter amp with a reduced noise...

I've modded a Ceriatone 2204 JCM800. I have to say the guys at Ceriatone has made a mighty fine job! Super clean work! Even though it looks very nice and neat there are improvements to be done to the tone and feel. Most of the preamp is rebuilt and there are some changes done...

Helping my friend to sell this Mesa Triple Rectifier. It's too aggressive for him and he wants a smaller and lighter amp. I modded this amp a few years ago and have made some upgrades to it now to make it more dynamic. Channel 1 is crispier and more open sounding and channel 2 and 3 are way...

This is a Marshall 2103 from 1979. It was a combo from the beginning but someone put the amp in an old Marshall headshell at some point.  It had some smaller modifications done to it. The whole preamp is removed and a board for the tube buffered effects loop is installed. The new...

I’ve modified a Marshall JMP 2104. The whole preamp section is rebuilt and I made some changes to the power amp and the power supply. This amp has dual footswitchable gain and volume controls + a footswitchable gain boost. So you can reach four different levels of gain using the footswitch. It...
