How we ranked these mic preamps
Every pick ranks in Amazon's best-seller list for its category and has a listing with real specifications. The order mixes two things: how each model compares on the specs below (higher share of the best value in this group scores more), and how widely it is bought. The spec score runs from 9.0 to 9.8 and only compares these picks with each other. A spec the listing does not state is left out and the other specs are re-weighted; a listing with fewer than 2 stated specs is scored at half. We do not test gear in person. Full method.

Buying advice: mic preamp with reverb
Count the inputs and outputs
A mic preamp needs the inputs your mic and sources use. The QST has dual 1/4 inch TS mic inputs, a 48V phantom powered XLR/TRS combo jack, optical and coaxial inputs, stereo RCA lines and Bluetooth. The SUNYIN and the YOVDA are on-board guitar pickups with Bluetooth, and the kousoer board has Bluetooth 5.0 and an AUX microphone input. Match the inputs to the gear you already own.
Check reverb, echo and EQ
Reverb sits on every pick here, but the controls differ. The QST adds built-in digital reverb, echo delays and parametric EQ, with feedback suppression that scans frequencies in real time. The SUNYIN and the YOVDA add delay, reverb and chorus with a mic function, and the SUNYIN adjusts effects with a rotary knob. The NGCG is a reverb plate only, with a depth resistor that takes a potentiometer from 20k to 50k. Compare the effects each unit gives before you buy.
Check power and the form factor
Form decides where the unit lives. The QST is a 1U rack-mount unit that fits 19-inch racks, while the SUNYIN is an on-board pickup that mounts on the guitar. The YOVDA is a vibration pickup with a sensor plate, and the kousoer is a board that runs on DC 8 to 36V. The NGCG is a 50 by 50 mm board that runs on DC 6 to 15V. Check the power your setup offers and the space the unit needs.
