    I have this system fitted to a KOPO Sassandra nylon string guitar ( and it produces wonderful tones, capturing the high and low frequencies beautifully. The volume wheel works well and is very useful for solo work – that extra boost when needed – and perfectly hidden inside the guitar’s sound hole.

    I did have a problem at first: the pre-amp socket developed a fault on the 48v power supply. But Fischer at Ischell very quickly supplied a complete new system and I am very pleased with the result. In fact I think the sound is better than before because I used a very skilled luthier to fit it this time; the position of the microphone is very important. Great service Ischell – thank you!!

    Sur mon ampli ACUS one Fourstring 5, le son original de ma guitare Martin OM 28 vintage se trouve pleinement restitué grâce au système Ischell Inside J48C9. Je recommande vivement ce produit, dont le rapport qualité-prix me parait amplement justifié.
    De plus, l’accueil et les conseils aident à réaliser un bon choix.

    Great microphone for my gypsy guitar, very resistant against feedback even at high stage volume levels!
