I just installed the PSP Old Timer Today, and it's the closest thing I've found to an instant 'make things better' compressor (especially for my vibe, which is warm, organic, singer songwriter country/folk/pop). It's what I've wanted from every LA-2A, Vari-mu compressor, and opto that I've tried.
PSP never ceases to impress me with the quality of their coding, their customer support, and loyalty discounts. I'm a PSP fan for life! This is an old thread - I'm curious to hear how many are still using old timer in 2024.
Honorable mention: I like the Neold U17, but more for the saturation/clipping section. Both plugins really help to bring an old school sound to my productions.
