SHADOW HILLS MONO GAMA api500

This is a Shadow Hills microphone preamplifier, now discontinued. It's an older model that has received high praise in reviews on overseas sites.
You can select between three modes: nickel transformer, steel transformer, and discrete mode which bypasses the transformers, and the sound quality clearly changes.
I've used many mic preamps, including those from other companies, but the richness of the sound is on another level compared to others. It's not just for microphones; it's far better for bass recording than the BAE I used previously.
I bought two because I liked it so much, but I need something with a completely different character, so I'm selling it. It functions without any issues. It's inherently robust.
The body is black, so reflections don't show up well in photos, but while there are some minor scuffs, I believe it's generally in good condition. Thank you for your consideration.
Please note that this item is also listed elsewhere, so there's a possibility it may be sold out due to a time lag.
I am not considering significant price reductions, so thank you for your understanding.
