About This Listing

For sale are HAND BUILT TO ORDER Hairball Audio Lola Mic Pres with JE990 Opamps. These preamps sound amazing and like no other! Dual John Hardy style 990 opamps with 1073 style Ed Anderson input and output transformers. If you're reading this than I am sure you know how
awesome and unique these pres are!

HAIRBALL HAS UPDATED THE LOLA FACEPLATE AND LEDS! I have added a photo of how your new Lola will look!


I am a trained professional tech as well as an engineer/producer here in Nashville, TN. I use high quality Kester solder and build these by hand. I fully test each preamp before sending out. Please allow 1 to 2 weeks for your order to be built.

I use Hairball's JE990 opamps which sound identical to the John Hardy 990s. (I can get genuine John Hardy 990s for a little more money, contact me before you order if you would like a different opamp besides the JE990.)

Make an offer if you would like more than one for an even better deal!

Here is some info from Hairball Audio:

The Lola maintains a completely differential signal path from input to output. The benefit to this topology is lower noise and a high CMRR. It also takes advantage of the excellent balance of the EA-10468 input transformer. In addition, because there are two op-amps in parallel, available output drive current is increased. This lowers output impedance; improving output transformer performance and increasing the maximum undistorted gain. In this regard it’s similar to running a single op-amp design on 24V rails.

The gain stage provides 65 dB of clean gain in 4.5dB steps utilizing a Grayhill rotary switch. The 600ohm; Bourns t-pad on the output allows the user to fine tune the gain setting. There are three illuminated pushbutton switches to select phantom power, phase and line mode. Activating the relay controlled line mode flips the input transformer making it a step down input. This allows the user to use the Lola on line level material. A pad has not been included due to the low ratio and large adjustable gain of the Lola. A 1:1.75 ratio input means the Lola has a lowest gain setting of 15.5dB reducing the need for a pad.

The DI accepts a ¼” unbalanced cable. Inserting a cable activates a relay that controls DI/Mic in circuitry. The DI passes through 2 FET buffers creating a differential signal to feed the 10468 input.

The light pipe LED meter has selectable VU and Peak metering. Though the VU mode is actually average metering (90% of RMS), it’s calibrated to VU metering with little effect on peak mode. 0dB on the meter scale represents +4 (1.23V) in VU mode. A simple resistor change allows the user to have 0dB equal to 0dB (0.775V) if preferred. Peak mode displays the peak value of the waveform in the same scale.

The front panel and L bracket are made in the USA . As a nod to the original 10468 input transformer, the durable front panel is finished with a “hammered” powder coat. The knobs are machined aluminum and have plenty of grip for the Grayhill rotary.
