Headway has recently added two new preamps to the product lineup.
The EDM-1 is a very compact 1 channel preamp suitable for both pickups and mics.
The EDB-2 will replace the well reviewed EDB-1. A 2 channel preamp with assignable EQ to either channel or both.
The EDB-1 is now discontinued but I have just bought one and will test it as soon as it gets here.
