Custom tube preamp & optocompressor

Description

TPC-I Sharonov Edition was designed at mr. Alexander Sharonov’s request, voice actor and audiobooks narrator.
Impressed with TPC-I mk2 capabilities, Mr. Sharonov soon became our endorser and asked for a few adjustments to the basic model that include:
1) a frequency selector for low pass cutoff which replaced the instrument input;
2) certain changes in the compression method.
Like with all custom-designed products, we put a lot of time and effort into it and even shipped it to Madrid a couple of times until we all agreed it was perfect.
Soon afterward the original device underwent a few modifications and is now known as TPC-I mk2 Sharonov edition holding a special place in our collection
