How we ranked these mic preamps
Every pick has at least 100 customer ratings on Amazon and 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.
- Max gain weight 2
- 48V phantom power weight 1
Buying advice: mic preamp for guitar
Count the models or bands
Model count and band count decide how much shaping you get. The FLAMMA holds 7 preamp models with 2 channels each, while the Fishman has 5 bands and the LIEKE has a 5-band equalizer. If you switch between amp sounds, more models help. If you shape one acoustic sound, band count matters more.
Check the output you need
Outputs decide where the preamp sends your signal. The Fishman has a balanced XLR out with a Pre/Post EQ switch, while the FLAMMA connects to a mixer or PA system through cabinet simulation. The LIEKE uses a 1/4-inch audio jack. Match the output to the next device in your chain.
Check power and weight
Power and weight decide how the preamp fits your rig. The FLAMMA needs a 9V DC supply over 303mA and weighs 0.7 lb, the Fishman weighs 1.8 lb and the LIEKE weighs 0.3 lb and runs on a 9V battery. Compare the power source and the weight before you buy.
