I think he said

Code: Select all

No, it is not associated with the AMT L1 series. It is a new development  - LIONSOUND14\0\DarkAngel/. And I took the cabsim from version 12 and added the headphone output from HotLine2.
Hmm, I remember DarkAngel modding the SansAmp GT2.
Seeing E530 written on the case and seeing Lionsound on guitar-gear.ru in the AMT stompboxes thread made me think this is related.
The "new development" part makes me think he just wanted to advertise his pedal.
uhhh i think that this pedal is from a russian guy, very clever in deep ,this is the link (in russian)
http://guitar-gear.ru/forum/topic/3724- ... _lionsound
and this is the schematcs from the ver 12
lionsound 12_0_final.gif
an the ver. 14 is a mod from darksid.very clever pedal and very clever mod too.

He says that he would like to share but the actual project is not his.

I may have a go at the cab simulator... looks interesting and I have heard samples of the previous version with direct recording in a mix, sounded excellent! I am guessing this version is geared more towards being used with an ENGL type preamp.. more mids.

I regularly frequent the guitar-gear.ru forum.. I already had the LS12 layout but have not built due to the odd components, 1208 programmable opamp and 2SK163... I think the UA776 or LM4250 may be suitable substitutes for the 1208 but not sure? I may have a go at the cab sim portion of the circuit, if I get around to it..?
It sounds really good to me but not so much to inspire me to investigate further...

Would prefer to see the schem for the LS14 ENGL sim... I LOVE anything ENGL!

Darksid46 - Maybe you can direct us to the mysterious forum or secret laboratory where the "LionSound 14" that you speak of lives? Is it being guarded by the Russian Yeti in some forsaken part of Siberia? :twisted:

Hi fellas

Awesome work on the Tight Metal! :applause:

Does anyone have a pcb available for sale or would someone be interested in making one for me? Thought about doing OSHPark but don't think Eagle or Gerber files are available. Thanks in advance for your help, feel free to pm me if you want... :D

I think it should work, correction are for tonestack. I've put two wrong junctions and rev1.1 should cover that. I've seen there are differences in your schematics.. Also I did layout with chargepump..

Wow ... what a thread. I read all 500 posts!!! Awesome work!!!

I just finished the TM and it sounds really GOOOOOD. Much better than all my commercial stomp boxes and anything I've ever diy-ed. It is brutal and yet natural both at lower volumes and cranked into a tube amp's return. There are a couple of things I wish to modify to my taste. Can anybody please help with advice and suggestions?

1. I don't like Noise Gate. Mine is wired to separate pot and seems to also lower the overall gain and distortion. It's audible even at low settings. The TM is actually quiet with a humbucker so I really don't need the gate that much. Just wondering if this is how it's supposed to work or is there something wrong with my parts or connections? Any links or suggestions for a mod that affects only the high frequencies?

2. Has anybody figured the exact purpose of the 1N4148 diode across V+ an V- of the first and third stages. Some posts suggest that they're for protection and others that they are for clipping. I'm asking because I generally do not like the way these sound as clippers and will consider getting rid of them.

3. The TM appears to distort more the lower frequencies and less the higher notes up the neck. This contributes to the more natural sound and to the fact that in open chords all notes are audible. I guess this is a result of the asymmetrical clipping of the zeners and the biasing of the clipping and the output stages. Is there a way to lessen this "effect" just a tiny bit so as to have more clipping at the higher notes . Should I try different zener values or experiment with the biasing of the clipping stages. What if I wired the output stage biasing with a trimmer. Will this enable me to "dial-in" different blends of the asymmetrically clipped negative and positive parts of the sine wave.

4. Has anybody tried a marshall type tone stack with the TM? Does it sound better? Any suggested values?

I will appreciate any advice and help! Thanks and cheers!

G.
