ALL.
heres a little challenge for the diy electronic gurus here.
(ive tried and failed on several occasions in the past.)
i call it the MOJO PRE. an in line 20 db mic pre with one xlr input, and line out to sound interface line in.
mojo pre has one control a "mojo pot". ie character.
specs.
1. easy to build low cost diy under 30 buks.
2. single low voltage supply. 9 volt battery would be great.
(with bipolar op amp supplies, one often ends up with too many darn components. and yes i know bout the 5 buckie mic pre.)
3. low component count.
4. maybe useing a low voltage cheap "new technology tube" or a couple of germanium transistors ?.
i'm not an electronics guru. lol.

my interests are songwriting crazy songs, singing,
jaunts/travel with my lovely wife who i adore and who spoils me rotten lol
(jaunts now limited due to covid. just got the pfizer jab. so far no side fx.)
just happy to be alive on this crazy planet after surgery over a year ago.
a particular interest of mine is researching space travel,
and whether certain types of future tech like magnetic propulsion might be the solution rather than current fuel technology. which i feel is old tech.
